Postoperative data

As to the postoperative chord mu, there was no statistically significant difference between the two groups (95% CI: -0.004 to 0.017; p=0.182); the same statistical findings regarding postoperative alpha distance were registered (95% CI: 0.000 to 0.00; p=0.067). Nevertheless, a statistically significant difference was found between pre and postoperative chord mu in each group (p<0.001), traducing a shorter distance between PC and FPR after surgery. Furthermore, when comparing the change in chord mu between groups, a statistically significant difference was found (95% CI: -0.026 to -0.002; p=0.022), with a higher change in the PC group (Table 2).
