Binary regression risk ratio (with 95% CI and p value) of achieving a minimum clinically important improvement in health status for IMD deprivation quintile relative to the reference group of least deprived IMD quintile for 3664 patients
| IMD quintile | Unadjusted risk ratio (95% CI) | After adjusting for baseline health status score quartile and PR programme clustering effects | After adjusting for baseline health status score quartile, patient-reported MRC dyspnoea score at initial assessment and PR programme clustering effects |
