\b[TODO: the effect-specific $F$ values are unavailable without the supplementary output.] Retrieve the rows for congruence, delay and congruence-by-delay <interaction>, if those terms were fitted. In an appropriate <analysis of variance>, each <F-test> compares a term's <mean square in ANOVA> with its designated error <mean square in ANOVA>; repeated observations can require different error terms. Neither the factor labels nor the recruited <sample size> determines those ratios.
