Serum sIL-2Rα levels for patients with acute brucellosis (pre- and post-treatment) and healthy controls. Circulating levels of sIL-2Rα in serum samples of patients with brucellosis (pre- and post-treatment, n = 30) compared to levels in healthy controls (n = 28), represented by dots. The horizontal line represents the median. A Mann-Whitney U-test was performed to evaluate the difference between controls and patients. Pre- and post-treatment levels were compared by the Wilcoxon matched-pair signed-rank test. sIL-2Rα: soluble Interleukin-2 receptor α; HC: healthy control
