From: The effect of ageing on human lymphocyte subsets: comparison of males and females

Distribution of percentages of PBL from individuals of different ages bearing different cell markers. The cell markers that PBL were stained for are shown on the Y axis. The linear regression results for all individuals (black line), males (blue line) and females (pink line) and the relevant P values are shown on the graphs. n.s. = not significant.
