Thirty-six patients who did not develop post-operative infection had CRP levels of 6 μg/mL in 31 (60.8%) and 12 μg/mL in five (9.8%). The p-value for the first postoperative day was 0.289 and statistically insignificant and on the third and seventh postoperative days was <0.001 and was found to be statistically significant. This evidence concerns the gene CRP and infection.
