We then built a prediction model using logistic regression and plotted a risk score based on these 7 features (p < 0.05): multispace involvement (OR 6.42, 95% CI 1.79–23.07, p < 0.001), gas formation (OR 4.95, 95% CI 2.04–12.00, p < 0.001), dyspnea (OR 10.35, 95% CI 3.47–30.89, p < 0.001), primary region of infection, NEUT% (OR 1.10, 95% CI 1.02–1.18, p = 0.015), PLR (OR 1.01, 95% CI 1.00–1.01, p = 0.010), and albumin (OR 0.86, 95% CI 0.80–0.92, p < 0.001) (Table 2). This evidence concerns the gene ALB and infection.
