B Body weight of Uqcrh -/- mice and wild-type littermates at 1-2 weeks (n = 5 to 10), during the post-weaning period from 5-6 weeks of age (n = 3 to 7) and weekly from 6 to 10 weeks (n = 13 to 66), data are shown as mean ± SD. **** p < 0.0001, 2-Way ANOVA, from 7.5wk of age for Uqcrh-/- males and females versus sex-matched controls. Data are shown as single data points and median, or categorical data, males and females pooled, since genotype-related effects were comparable for both sexes from different cohorts. * p < 0.05, *** p <0.001, Wilcoxon rank-sum test.
