The multivariate analysis identified several independent risk factors: duration of symptoms (Odds Ratio [OR] = 2.14; 95% Confidence Interval [CI], 1.03–5.23; P = 0.0015), presence of gross bloody stool (OR = 8.98; 95% CI, 1.76–48.75, P < 0.001), elevated C-reactive protein levels (OR = 4.79; 95% CI, 1.12–28.31, P = 0.0072), lactate clearance rate (LCR) (OR = 17.25; 95% CI, 2.36–80.35; P < 0.001), and the location of intussusception (OR = 12.65; 95% CI, 1.46–62.67, P < 0.001) (Table 3). This evidence concerns the gene CRP and Intussusception.
