Supplementary Figure 6: Selection criteria for interaction between immune parameter and aging.
From: The cellular composition of the human immune system is shaped by age and cohabitation

Determination of significance threshold for correlations between immune parameters and age. (a) Density plot of distribution of the adjusted P values, with P=0.05 and 0.01 shown by the dashed and solid lines respectively. P=0.01 better describes the lower tail of the distribution.(b) Adjusted P values plotted against Spearman’s correlation coefficient. 0.01 < P < 0.05 have low correlation coefficients values, supporting an exclusion threshold ofP < 0.01.
