AM, time-adjusted mean; AUC, area-under-the-curve; CAD, coronary artery disease; DBP, diastolic blood pressure; SBP, systolic blood pressure; SLEDAI-2K, Systemic Lupus Erythematosus Disease Activity Index 2000; TC, total plasma cholesterol (mmol/L). aMenopause defined as a minimum of 12 months of amenorrhea irrespective of cause. bYears. cScores range from 0 to 105, with higher scores indicating more-active disease. dDisease manifestations defined based on SLEDAI-2K definitions. eChronic renal insufficiency defined based on SLICC/ACR DI definition (glomerular filtration rate < 50%, proteinuria ≥3.5 g/24 h, or end-stage renal disease). fMeasured by using commercial assays, with test reported positive if either IgM or IgG antibody level exceeded manufacturer-recommended cut points. gAntimalarials include chloroquine and hydroxychloroquine. hImmunosuppressives include methotrexate, azathioprine, mycophenolate mofetil, cyclosporine, and cyclophosphamide. iHypertension was defined as DBP ≥90 or SBP ≥140 mm Hg or treatment with antihypertensive medication. jHypercholesterolemia was defined as TC > 5.2 mmol/L or lipid-lowering therapy. kDiabetes was defined as fasting plasma glucose > 7.0 mmol/L or diabetes therapy. lCurrent smoking is defined as smoking of an average of one or more cigarettes per day over the past month. mAll classes of antihypertensives including diuretics, β-blockers, calcium channel blockers, angiotensin-converting enzyme inhibitors, and angiotensin type II receptor blockers. nHMG Co-A reductase inhibitors (statins). ommol/L. pmmol/L multiplied by months. |
