Fig. 2From: Aging and CMV discordance are associated with increased immune diversity between monozygotic twinsEuclidean distances between twins and between demographically similar non-twins (matched CMV status to twin and within +/− 5 years of age) over age. Each dot represents a pairwise distance for the twins or the median of the pairwise distance of repeated random matching of demographically similar non-twins, over (a) all cell subset frequencies, (b) CD4+ T cells, or (c) CD8+ T cells. 95% confidence intervals are shown by the shaded areas around the lines of best fitBack to article page
