Fraction of MG relative to the total glial pool in occipital cortex samples from CHIP and non-CHIP donors, computed from frequencies of the indicated clusters. Two-sided Wald P value = 0.042 by quasibinomial regression of the cell counts of MG, oligodendrocytes and astrocytes. n = 10 donors. Box plot shows median, first quartile and third quartile. Box plot whiskers show minimum and maximum values, which are capped at a distance of 1.5 (interquartile range) away from the box. The colors in d – g represent the sample name as depicted in the box under Fig. 4b . Detailed information for each donor is available in Supplementary Table 14 . Samples are unsorted and are taken from the occipital cortex unless otherwise indicated. Ce, cerebellum; P, putamen.
