Abbreviations: NPRS is numeric pain rating scale; SF-MPQ is MPQ Sensory subscales; BFI is brief fatigue inventory; PWB is BREAST-Q upper body and chest wall physical well-being scale. TE/I is tissue expander/implant reconstruction; DTI is direct to implant reconstruction; p-TRAM is pedicled transverse rectus myocutaneous flap; DIEP is deep inferior epigastric artery perforator flap; f-TRAM is free transverse rectus myocutaneous flap; SIEA is superficial inferior epigastric artery flap; lat dorsi is latissimus dorsi myocutaneous flap.
Adjusted for baseline values of the outcome variable, age, BMI, education (3 levels), income (3 levels), race (as White, Asian, black and other), ethnicity, laterality, timing, and axillary surgery and for within-study center correlation and predicted at mean covariate values.
Testing for differences in adjusted means across procedure types using score test (Type III test)
NOTE: For NPRS, MPQ, BFI, and PROMIS-29, a higher value corresponds to more pain or fatigue. For PWB, a higher value corresponds to better physical well-being or less physical distress.
