GEE, generalized estimating equation; CI, confidence interval.

aAll variables measured coincident with measurement of total cholesterol.

bSLE Disease Activity Index 2000; scores range from 0 to 105, with higher scores indicating more-active disease.

cAntimalarials include chloroquine and hydroxychloroquine.

d Immunosuppressives include methotrexate, azathioprine, mycophenolate mofetil,

cyclosporine, and cyclophosphamide.

eAntihypertensives include all classes of drugs used to lower blood pressure.

fHypertension is defined as systolic BP ≥ 140 mm Hg or diastolic BP ≥ 90 mm Hg.

gEstrogen with/without progestin hormone-replacement therapy.
