Residual activation capacity of the complement system in patients with NSTI and in non-infected control patients. Values denote medians with IQR. Differences were analyzed with the Mann-Whitney U test. Assessment of classical pathway activity was performed on anti-human albumin/albumin immune complexes (plasma samples diluted 1:400), ficolin-mediated lectin pathway activity on acetylated BSA (plasma samples diluted 1:1,000) and alternative pathway activity on lipopolysaccharide (plasma samples diluted 1:10).
