Cytokine levels in patients with systemic lupus erythematosus (SLE), healthy controls (HC), and patients with other autoimmune diseases (AIDs). Comparator groups included SLE, including active and inactive SLE, primary antiphospholipid syndrome (pAPS), AIDs other than SLE (mixed connective tissue disease, pAPS, primary Sjögren’s syndrome, rheumatoid arthritis, or systemic sclerosis), and HC. The latter group for each comparison was used as reference. Red and blue colours denote upregulation and downregulation of cytokines, respectively. Comparisons with insufficient observations are indicated in grey. p values are derived from Mann-Whitney U tests. Statistically significant differences are denoted by asterisks.
