Results of linear regression modeling, excluding those unexposed to any ARVs during pregnancy (N = 18). Each row represents a separate linear regression model comparing youth exposed in utero to HAART with those unexposed to HAART.
Adjusted for age, sex, race/ethnicity, BMI Z-score, and SBP Z-score; diastolic function measures also adjusted for heart rate.
BMI, body mass index; D, diastolic; ED, end-diastolic; ES, end-systolic; LV, left ventricular; S, systolic; SBP, systolic blood pressure.
