SF-12 and disease-specific HRQL measures comparing outcomes between patients undergoing Heller's myotomy (reference value) and pneumatic dilatation or both Heller's myotomy and pneumatic dilatation
| Heller's myotomy (n = 43) | Pneumatic dilatation (n = 44) | Both treatments (n = 33) | |||
|---|---|---|---|---|---|

†Adjusted for age, sex, and time since treatment. Bold represents significant results. ASQ, Achalasia Severity Score; CI, confidence interval; HRQL, health-related quality of life; MCS-12, Mental Component Summary score; PCS-12, Physical Component Summary score; SD, standard deviation; SF-12, Short Form Health Survey.
