Table S2. Comparison of surgical and SBRT groups before and after propensity matching on baseline QoL.
| Quality of life | Before propensity matching, mean (SD) | After propensity matching*, mean (SD) | |||||
|---|---|---|---|---|---|---|---|
| Surgery | SBRT | P value | Surgery | SBRT | P value | ||
| PCS | 39.6 (11.8) | 32.9 (10.2) | 0.0061 | 32.5 (13.9) | 33.6 (10.8) | 0.7628 | |
| MCS | 52.3 (10.0) | 43.8 (14.4) | 0.0056 | 51.2 (11.0) | 45.1 (14.9) | 0.1553 | |
Before propensity matching, n=184 (156 surgery, 28 SBRT); After propensity matching, n=44 (22 surgery, 22 SBRT). *, matched on age at diagnosis, gender, race, education, smoking status, whether the baseline survey was completed by proxy, and presence of COPD/emphysema/asthma, and angina pectoris/CAD. COPD, chronic obstructive pulmonary disease; CAD, coronary artery disease; PCS, Physical Component Summary; MCS, Mental Component Summary; SBRT, stereotactic body radiation therapy; SD, standard deviation.
