In multivariate analysis, out of clinical variables reportedly associated with an increased risk of prolonged postoperative ileus and relevant chemokine data, dichotomized length of surgery and MCP-1 concentration at 24 h were selected as independent predictors of RoBF ≥ 5 days, displaying 73% accuracy, 100% sensitivity, and 43% specificity (Table 4). The gene discussed is CCL2; the disease is ileus.
