Values are expressed as median with IQR in parentheses, unless otherwise stated.
*P values are calculated by univariate analysis, Wilcoxon rank sum test, except for binary variables calculated by Fisher’s exact test (p*).
CL-K1, Collectin-Kidney 1; CRP, C-reactive protein; ESR, erythrocyte sedimentation rate; MASP-3, mannan-binding lectin associated serine protease 3.
