Preoperative neutrophil-to-lymphocyte ratio predicts symptomatic anastomotic leakage in elderly colon cancer patients: Multicenter propensity score-matched analysis

Figure 1 Study population enrollment process. NLR: Neutrophil-to-lymphocyte ratio.

Figure 2 Receiver operating characteristic curve analysis of the ability of preoperative neutrophil-to-lymphocyte to predict symptomatic anastomotic leakage. AUC: Area under the curve; CI: Confidence interval.

Figure 3 Comparison of the incidence of symptomatic anastomotic leakage between the neutrophil-to-lymphocyte ratio < 2. 66 and neutrophil-to-lymphocyte ratio ≥ 2.66 groups before and after propensity score matching. A: Before propensity score matching; B: After propensity score matching. NLR: Neutrophil-to-lymphocyte ratio; OR: Odds ratio; CI: Confidence interval.
