Network meta-analysis on overall survival. (a). Forest plots of network comparisons between treatments. (b). Pooled hazard ratios with 95% CrI for each comparison arm. The pooled hazard ratio with 95% CrI was estimated under the Bayesian framework. Data in each cell are hazard ratios (95% credible intervals) for the comparison of row-defining treatment versus column-defining treatment. Bold text indicates a statistically significant difference. Abbreviations: NCRT: neoadjuvant chemoradiotherapy. NCT: neoadjuvant chemotherapy. S: surgery. 95% CrI: 95% credible intervals.
