Length time bias is a phenomenon that can occur in the evaluation of medical screening methods or tests, particularly in the context of cancer screening. It occurs when the screening process disproportionately identifies slower-growing, less aggressive forms of a disease compared to more aggressive forms that may present differently. This can give a misleading impression of the effectiveness of the screening program and the overall prognosis of patients whose diseases were detected through screening.

A multiple of the median refers to a value that is obtained by multiplying the median of a dataset by a certain factor or integer. The **median** is the middle value of a sorted dataset, and if the dataset has an even number of observations, the median is the average of the two middle values. For example, if the median of a dataset is 10, then: - A multiple of the median for factor 2 would be \(2 \times 10 = 20\).

Passing-Bablok regression is a non-parametric statistical method used to assess the agreement between two different measurement methods or instruments. It is particularly useful in situations where the data may not meet the assumptions of normality or homoscedasticity required by traditional linear regression methods.
