Perioperative deaths and deaths caused by infection were associated with higher CRP values on days 4, 6, and 7 (8.41–12.44 mg/dL versus 3.08–5.74 mg/dL, p < 0.05) and with lower CRP values on the 1st day in the case of perioperative deaths (5.98 mg/dL versus 9.53 mg/dL, p < 0.05) and overall deaths (7.27 mg/dL versus 10.38 mg/dL, p < 0.05). This evidence concerns the gene CRP and infection.
