All the variables are represented as mean±SE except HOMA-B, HOMA-IR, DI and Matsuda Index, which are represented as geometric mean±SE. P value for multigroup comparisons done using one-way analysis of variance. Log transformation done for HOMA-B, DI, HOMA-IR and Matsuda index before comparison.
HbA1c, glycated hemoglobin; HOMA-B, homeostatic model assessments of beta-cell function; HOMA-IR, homeostatic model assessment of insulin resistance; T2DM, type 2 diabetes mellitus.
