16 proteins with statistically significant (BH-FDR < 0.05) Spearman correlation of study site effect in the two sets of samples from the translational study are predominantly those that achieve higher statistical significance for the main effect of time in the designed study of blood processing factors; additionally, they also, to a smaller degree, tend to demonstrate greater significance for the effects of interaction between time and temperature and temperature and heparin/EDTA type of anticoagulant. Left panel represents ranks of p-values for those 16 proteins across p-values of all proteins for the effect of corresponding study factor—values close to zero correspond to smaller, more significant, p-values; right panel summarizes each scatter on the left as one-sided Wilcoxon p-value representing probability of obtaining sum of ranks lower than observed value by chance
