Mean values and standard deviations of BRS parameters. Given p values are results from Kruskal-Wallis tests. The first three p values target transversal comparisons, and the last p value (last column) shows the results of the longitudinal, i.e., within surgical procedure, analysis. Results of transversal post hoc tests are shown in Figure 5). Results of longitudinal post hoc tests are given in Table 4.
