Compared with critically ill patients without sepsis, sepsis patients had higher PCT (28.11 ± 32.78 vs. 3.01 ± 5.77, p = 1.95 × 10−4), CRP (153.83 ± 78.66 vs. 74.05 ± 65.31, p = 4.19 × 10−4) and creatinine (154.95 ± 125.86 vs. 84.22 ± 98.58, p = .025) levels. This evidence concerns the gene CRP and Sepsis.
