Input variables: age, gender, family history of T2DM, family history of dyslipidemia, PI duration, lipohypertrophy, and exposure to stavudine ≥6 months. Fisher’s exact test. Viral load ≤ 40 copies/mL was expressed as 40 in the statistical analysis. OR, odds ratio; CI, confidence interval; IQR, interquartile range; CVD, cardiovascular disease; HT, hypertension; T2DM, type 2 diabetes mellitus; SBP, systolic blood pressure; DBP, diastolic blood pressure; CDC, Centers for Disease Control; FPG, fasting plasma glucose; PG, plasma glucose.
