Note: values are unadjusted mean ± SD for continuous variables or (%) for categorical variables. Diabetes medication is only for cases. So statistical test is not necessary and the value is not available (NA). Cases: with T2D; controls: without T2D; BMI: body mass index; diabetes meds: diabetes medications; SBP: systolic blood pressure; DBP: diastolic blood pressure.
