Kaplan-Meier survival curve for septic patients at 28 days according to the MBL level. (a) The difference for 28-day mortality was not found in all patients according to serum MBL levels (MBL <1.3 μg/mL and MBL ≥ 1.3 μg/mL). (b) In subgroup analysis, the difference for 28-day mortality within septic shock patients was more pronounced (P = 0.020). A low MBL level (<1.3 μg/mL) was an independent risk factor for mortality after 28 days within the septic shock group. There was a hazard ratio of 0.571 (95% confidence interval, 0.355 to 0.916; P = 0.020) in the Cox proportional hazards model correcting for age, sex, and comorbidities. MBL = mannose-binding lectin.
