MKI67 and obesity due to melanocortin 4 receptor deficiency: A relevant result was obtained by two-way ANOVA of the number of Ki67-positive cells in lymphoid follicles: significant effects of obesity (F (1, 84) = 8.171; p = 0.0054), OEA-DS administration (F (1, 84) = 34.74; p < 0.0001), and their interaction (F (1, 84) = 16.92; p < 0.0001) were found.
