Surgeons’ opinions about enhanced recovery after surgery for retroperitoneal sarcoma: A survey

Figure 3 Distribution of the intra-observer reproducibility over the whole survey, considering feasibility and relevance, respectively, and according to the four different domains (preoperative, anesthesiology, intraoperative, and postoperative). Each box indicates the 25^th and 75^th percentiles. The horizontal line in the box indicates the median, and the whiskers indicate the extremes. The dotted line indicates the weighted kappa value of 0.70- i.e., a “quite satisfactory” level of reproducibility.
