IDI, though not significant, showed a trend of improved classificatory ability compared with Model 1 (NRI [95% CI], 0.74 [0.31, 1.17], P < 0.001; IDI [95% CI], 0.05 [-0.01, 0.12], P = 0.126).

We next separately assessed sC5b-9 levels in PDF from cases grouped by causative microorganism (including culture negatives) to assess whether this finding was organism-specific; adjusted sC5b-9 levels in PDF from group 1 cases were significantly increased compared with group 2 in culture negative peritonitis but in other groups failed to reach significance likely because of sample size limitations.
