Table S4: Nonparametric testing of experimental data. n is the number of groups in each condition; ¯ δ is mean group shift taken over the n groups; SE, CI, and p ( ¯ δ ) are its standard error, 95% confidence interval, and p-value; Δ ¯ δ is the difference between the ¯ δ values of the comparison pair and p (Δ ¯ δ ) is its p-value. Statistical quantities are calculated using bootstrapping with one million resamples. For testing Δ ¯ δ , the comparison pair samples were pooled.
