When patients in the Obese BS group were further classified as MetS (n = 4), T2D (n = 7), and none (n = 2), they all had a higher mean ND1/18S rRNA ratio in PBM cells than HC, but the differences were not statistically significant, probably due to small sample sizes (Supplemental Figure S4B, Supplemental Table S4). This evidence concerns the gene MT-ND1 and metabolic syndrome.
