Odds ratios for newly diagnosed diabetes based on different levels of SFA and VFA. Solid lines are multivariable-adjusted odds ratios, and dashed lines indicate 95% confidence intervals derived from restricted cubic spline regression. Odds ratios are plotted on a log scale. Odds ratios of SFA and VFA for newly diagnosed diabetes after adjustment for age, level of education, smoking habit, alcohol consumption, leisure-time physical activity, systolic blood pressure, and family history of diabetes (Model 2) are presented in a, b for men, and e, f for women, respectively. Odds ratios of SFA and VFA for newly diagnosed diabetes after adjustment for variables in Model 2 and also for body mass index as well as VFA or SFA (Model 4) are presented in c, d for men, and g, h for women, respectively. BMI body mass index, SFA subcutaneous fat area, and VFA visceral fat area
