  • Multivariable regression models adjusted for the following variables: age, sex, race, education level, marital status, employment status, comorbidity, ADL limitation, and current smoking status. HRQOL: health related quality of life; PCS: physical component summary; MCS: mental component summary;ADL: activity of daily living; NS: not significant (p ≥ 0.05).
