Timing of surgery after neoadjuvant chemoradiotherapy affects oncologic outcomes in patients with esophageal cancer

Figure 1 Flow chart of study selection.

Figure 2 Forest plot of the association between time interval and overall survival/progression-free survival of esophageal cancer patients.

Figure 3 Forest plot of the association between time interval and overall survival of patients with squamous cell carcinoma and adenocarcinoma.

Figure 4 Sensitivity analysis of the association between time interval and overall survival. Combined results were still stable after the exclusion of any single study.

Figure 5 Begg’s funnel plot of the association between time interval and overall survival. The Begg’s funnel plot did not indicate publication bias in the meta-analyses on the association between time to surgery and overall survival (Pr >|z| = 0.344 for Begg’s test).
