Values are presented as mean ± standard error (SE). Postoperative Date; POD, p # represent overall differences according to time as determined using the repeated measures of ANOVA, * p < 0.01 vs. Baseline, ** p < 0.001 vs. Baseline, + p < 0.01 between the affected and unaffected side (POD1 to POD 24 adjusted for Baseline value).
