Network meta-analysis of randomized controlled trials on esophagectomies in esophageal cancer: The superiority of minimally invasive surgery

Figure 3 Operation time was significantly shorter for transhiatal approach compared to transthoracic surgery, hybrid intervention, minimally invasive technique, and robot-assisted esophagectomy. A: The network of eligible studies for operation time [the width of the lines is proportional to the number of trials comparing every pair of treatments, and the size of every circle is proportional to the number of randomly assigned participants (sample size)]; B: League table of the analysis for operation time. Comparisons should be read from left to right. The values are presented in weighted mean difference (minutes), with corresponding credible interval. Significant results are in bold and underlined; C: Cumulative probability of interventions rank; D: Intervention ranking in surface under the cumulative ranking (SUCRA)% histogram.
