  1. Abbreviations HI: healthy individuals; ACR: American College of Rheumatology; SLICC: Systemic lupus international collaborating clinics; MADRS-S: Montgomery-Åsberg Depression Rating Scale, self-reported; SDI: SLICC/ACR damage index; SLEDAI-2 K: SLE-disease activity index 2000; DMARD: disease-modifying anti-rheumatic drug
  2. 1Education status is divided into 3 levels: 1 for comprehensive school (year 1–year 9) or lower, 2 for having completed upper secondary school (year 10–year 12), and 3 for having completed higher educational levels (university college/ university bachelor’s level or higher)
  3. 2MADRAS-S score is significantly (p < 0.001) higher in the SLE patients compared to HI
  4. 3SDI score ranges from zero (no organ damage) to 47 (highest possible level of damage)
  5. 4SLEDAI-2 K ranges from zero (no disease activity) to 105 (highest possible level of disease activity)
