Fig. 3. Interaction of circulating 25(OH)D, as a categorical variable, with IRS1 variant on HOMA-IR in BPRHS and MESA Hispanic women. In BPRHS, minor T homozygotes of rs2943641 had higher HOMA-IR than C carriers only when circulating 25(OH)D was higher than the population median (P = 0.036).

In the MESA Hispanic, minor C homozygotes of rs2673142 had higher HOMA-IR than G carriers only when circulating 25(OH)D was higher than the population median (P = 0.039). The P values of the interaction were calculated in a general linear model by including an interaction term [genotype by 25(OH)D] in the model. Number inside the bar indicates the number of subjects in that group. Values are means ± SE.
