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

Figure 1 PRISMA flow diagram of literature search and review. ERAS: Enhanced recovery after surgery.

Figure 2 Heatmap representing an overview on response to the survey. On the vertical axis, the different observer over the two rounds of the survey; on the horizontal axis, the items proposed (R, relevance; F, feasibility). Color scale: Red, rating Low (score 0-1); yellow, rating Moderate (score 2-3); green, rating High (score 4-5); grey, Not Available (bimodal distribution in reference modal value; no rating given in observer axis).

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.

Figure 4 Item-level bar plot. Each bar reports the observed concordance in terms of absolute frequency. The higher is the bar, the stronger is the observed agreement. A: Intra-observer concordance evaluation between the first and second round; B: Concordance evaluation vs reference in the first round; C: Concordance evaluation vs reference in the second round.
