RETN and type 2 diabetes mellitus: The adiponectin-resistin (AR) index was more strongly associated (df = 3; F = 70.494; P = 1.77 × 10-40) with increased risk of type 2 diabetes (T2DM) and metabolic syndrome (MS) than adiponectin (df = 3; F = 13.900; P = 7.65 × 10-9) and resistin (df = 3; F = 49.165; P = 3.52 × 10-29) levels alone (Figure 1, Figure 2 and Figure 3).
