  1. Beta coefficients represent the relation of SLICC, Katz, and SLEDAI score (independent variable) to each of the lipid profile molecules including ApoC3 (dependent variables). Significant p values are depicted in bold
  2. LDL low-density lipoprotein, HDL high-density lipoprotein, SLEDAI Systemic Lupus Erythematosus Disease Activity Index, SLICC Systemic Lupus International Collaborating Clinics/American Colleague of Rheumatology Damage Index
  3. #1 adjusted for age, BMI, systolic blood pressure, and statins
  4. #2 adjusted for age, BMI, systolic blood pressure, and statins, plus any lipid profile molecule that has a univariable relation with the score inferior to 0.20
  5. *Adjusted for age, BMI, systolic blood pressure, and statins + HDL cholesterol; **adjusted for age, BMI, systolic blood pressure, and statins + cholesterol, HDL cholesterol, and apolipoprotein A1
