Correlation of growth arrest-specific gene 6 protein (GAS6) and sTyro3 with Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). Systemic lupus erythematosus (SLE) patients were classified according to SLEDAI into a low (n = 18), intermediate (n = 22) or high activity group (n = 10). Values were significantly different using analysis of variance (ANOVA) (GAS6, P = 0.015; sTyro3, P = 0.021).
