All MV models were adjusted for the same covariates as in Table 3. At baseline, the number of participants in each alcohol category was as follows: 53,102 for alcohol intake 0 to <5 g/d with the number of participants from quintiles 1 to 5 of GI being 9383, 9954, 10,460, 11,187, and 12,118, respectively; 18, 681 for alcohol intake 5 to <15 g/d with the number of participants from quintiles 1 to 5 of GI being 4130, 4149, 3859, 3597, and 2946, respectively; and 10,044 for alcohol intake ≥15 g/d with the number of participants from quintiles 1 to 5 of GI being 2718, 2279, 2034, 1667, and 1346, respectively. P-interaction = 0.76. GI, glycemic index; MV, multivariate; T2D, type 2 diabetes.
