aP values were obtained from repeated-measures analysis of variance with the Greenhouse-Geisser adjustment because of failure of sphericity via the Mauchly test. Main effects for time were assessed for mean equivalence via least significant difference–adjusted pairwise tests. Statistically significant difference between preoperative and postoperative values are noted in bold. Significant mean differences on pairwise testing are indicated via italics, with individual P values listed below each time point compared with 2 years before surgery.
