Gender disparity in the odds ratio for the association between obesity and T2DM among three age groups. The odds ratio for men and women was estimated by logistic regression and the SWAN algorithm, as stratified by age. A comparison of the odds ratios between men and women was performed for each age window and connected by grey lines. The difference of odds ratio in each age group was tested by the Wilcoxon test.
