The standard deviations of protein property values for each annotated complex are significantly smaller than ones for model 1 random complexes (MC-test using 1000 complexes generated randomly with replacement: P < 0.001). The means ± standard deviation of these standard deviations for each property are shown in the last two columns along with median values (in parentheses).
