List of physicians

Joann G. Elmore is a physician whose research examines variability in cancer diagnosis, including how consistently pathologists classify biopsy material. Her research group's description connects that work with statistics and machine learning for evaluating diagnostic decisions.^[ref]

In a 2017 primary study, Elmore and colleagues assembled 240 skin biopsy cases and gave participating pathologists sets of 36 or 48 cases. The design included a second interpretation of the same cases at least eight months later; 187 pathologists completed 8,976 interpretations in the first phase. Comparing an observer with their own later reading, with other observers and with a reference panel answers three different questions about statistical classification.^[ref]

The distinction is within-observer agreement versus reference agreement. In an illustrative set of 20 cases, an observer might repeat 18 of their earlier classifications but agree with a reference classification on only 14: the two proportions are $18/20=90\%$ and $14/20=70\%$. Repeating the same erroneous category increases the first proportion without improving the second. These are invented counts to explain the design, not results from Elmore's study. A consensus reference is an explicitly defined comparison standard; it does not make a panel infallible, and the diagnostic mix of a selected test set must be considered before interpreting an overall agreement percentage.

W. E. Siegenthaler coauthored the 1979 primary evaluation of coronary angioplasty with A. R. Grüntzig and A. Senning. The published byline records these initials. The report combined a clinical case series with measurements of the narrowed vessel and its pressure drop, and explicitly called for a prospective randomized comparison with surgical and medical management.^[ref]

This contribution illustrates a distinction between demonstrating that an intervention can change a physical obstruction and establishing how its outcomes compare with alternatives. A selected series can document feasibility and observed complications. It does not automatically supply the outcomes that the same patients would have had under another treatment.

The report's 32 technical successes among 50 treated patients give the observed fraction $32/50=0.64$.^[ref] That denominator is the treated series, not every person with coronary artery disease or everyone considered for an intervention. Eligibility, selection and the definition of success determine what the fraction describes.

An original case mix example shows why a comparison can change even if subgroup responses do not. Suppose a hypothetical endpoint occurs with probabilities $0.9$ and $0.5$ in two patient groups. A series containing $80\%$ from the first group has modeled ratewhereas a series containing only $20\%$ from that group has rate $0.58$. The difference $0.24$ was created entirely by group composition in this model. It is not a treatment-effect estimate or a result attributed to Siegenthaler.

A clinical trial with a justified comparison addresses a different question from a selected feasibility series. Randomized experiment design helps control treatment assignment; follow-up and endpoint definitions still need scrutiny. Siegenthaler's jointly authored report is scientifically notable for presenting the initial clinical evidence while recognizing the further comparative evidence required.

A. R. Grüntzig is the first author of the 1979 primary report on coronary angioplasty coauthored with A. Senning and W. E. Siegenthaler. The report describes introducing a catheter through a systemic artery and dilating a narrowed coronary artery by controlled inflation of a balloon catheter under local anaesthesia.^[ref]

The apparatus links geometry and physiology: a distensible balloon changes a local narrowing, while measurements test the result. In the successful cases, the authors reported mean stenosis changing from $84\%$ to $34\%$ and mean coronary pressure difference from $58$ to $19\mathrm{mmHg}$.^[ref] These are paired observations within the reported successful group, not mean outcomes for every attempted procedure or a randomized comparison.

The arithmetic distinguishes percentage points from relative changes. The reported stenosis values differ by 50 percentage points; relative to the initial value, the numerical reduction isFor the pressure difference, the analogous reduction is $(58-19)/58\simeq 0.672$. The two calculations describe different observables and need not yield the same fraction. Neither calculation alone establishes a corresponding change in survival or overall health.

An ideal fluid-mechanical model helps motivate measuring pressure as well as geometry. For steady laminar flow through a uniform rigid tube, Hagen-Poiseuille equation givesAt fixed dynamic viscosity $\mu$, length $L$ and volume flow rate $Q$, increasing radius by a factor $1.2$ reduces the modeled pressure difference to $1/1.2^4\simeq 0.482$ of its former value. This is an illustrative sensitivity calculation, not a reconstruction of a living coronary artery, whose geometry, wall motion and flow conditions are more complicated.

Grüntzig's joint report makes the mechanical intervention experimentally testable through multiple readouts. Interpreting those readouts still requires attention to failed attempts, complications, follow-up and selection. A physically effective local change and a favorable comparative clinical outcome are related hypotheses requiring different evidence.

G. A. Wheeler coauthored a 1915 dietary experiment with Joseph Goldberger investigating the cause of pellagra. The study followed prisoners in Mississippi after placing them on a restricted diet dominated by cereal foods. Eleven remained in the experiment to its end; the authors reported symptoms sufficient for a diagnosis of pellagra in at least six. Other prisoners under observation did not develop comparable evidence of the disease.^[ref]

The comparison mattered because it changed food intake while observing people in the same broad setting. The findings supported a dietary explanation without identifying the particular missing nutrient. They should not be read as a population-wide disease probability: a small, selected group subjected to a particular intervention answers a narrower question. The report also records that participation followed an offer of a pardon, which is essential context for interpreting its use of the word “volunteer”.^[ref]

Joseph Goldberger investigated pellagra as a disease of inadequate nutrition when an infectious explanation was widely accepted. His work helped shift the question from which organism transmitted the disease to what was missing from the diet. He established a dietary explanation without isolating the specific protective nutrient; vitamin B3 was identified as the missing component later. ^[ref]

With G. A. Wheeler, Goldberger reported a 1915 experiment in which a restricted diet produced pellagra in at least six of eleven prisoners who completed the study. Their report compared the experimental group with other prisoners, considered differences in work and hygiene, and concluded that the restricted diet caused the disease.^[ref]

The scientific lesson is to separate association, intervention and identification of a mechanism. Observing that a disease clusters among people eating similar foods suggests a hypothesis. Changing the diet tests that hypothesis more directly. Identifying the missing vitamin is a further chemical step, requiring evidence beyond the original feeding comparison.

Adam L. Bartret led a radiological study testing whether variant sciatic nerve routes near the piriformis muscle were associated with piriformis syndrome. The researchers classified anatomy on 783 hip magnetic resonance imaging studies and compared recorded clinical diagnoses. Variants occurred in about 19% of hips, with no statistically significant diagnostic association in this cohort.^[ref]

The study illustrates the distinction between identifying an anatomical variant and showing that it causes pain. A visible difference can be incidental; conversely, this observational result does not establish that every possible compression mechanism is absent.

Steven E. Schraffordt led a dissection study of the pudendal nerve and its terminal branches. Examination of 28 cadavers documented variations relevant to the motor supply of the external anal sphincter. In five specimens, interconnecting inferior rectal and perineal branches formed a local nerve plexus near the sphincters.^[ref]

This is a practical contribution of anatomical observation: an intact muscle can lose function if its nerve supply is injured. A schematic branching pattern therefore needs to be interpreted alongside documented variation when considering pelvic anatomy.
