Low levels of Bregs were associated with an increased risk of death in patients with sepsis. A Frequency and B absolute number of Bregs in sepsis patients were decreased in dead patients. C PCT, D CRP, E lactate, F creatinine, G bilirubin, H APACHE II, and I SOFA were compared between alive and dead groups. Two-tailed t-test with unequal variance or Kruskal–Wallis test. *p < 0.05; **p < 0.01; ***p < 0.001
