Abbreviations: SF-36v2, Medical Outcomes Study 36-Item Short-Form Health Survey, version 2; SD, standard deviation; PCS, physical component summary; MCS, mental component summary.

^*Adjusted for age, Charlson-Deyo comorbidity score, income, work status, and history of radiation treatment. Negative adjusted difference indicates lower quality of life (QOL) for cases. Although not shown, similar results were obtained when analyses were adjusted for time since surgery in addition to these primary adjusters.

^†Exceeds minimally important difference.

^‡Statistically significant after Bonferroni adjustment (adjusted alpha = .05/8 = .00625).

^§Standardized physical component summary score.

^¶Statistically significant (P < .05) with no Bonferroni adjustment.

^∥Standardized mental component summary score.
