IPTW-weighted Cox Proportional Hazard models for 2-year mortality and 1-year all-cause and respiratory-related hospitalisation
| All patients | Subgroup analyses | |||
|---|---|---|---|---|
| Idiopathic interstitial pneumonia | Sarcoidosis | Other interstitial lung diseases | ||
| HR (95% CI) | HR (95% CI) | HR (95% CI) | HR (95% CI) | |
| 2-year all-cause mortality | ||||
| Specialised ILD centre vs. non-specialised centre | 0.87 (0.78, 0.96)* | 0.81 (0.70, 0.94)* | 0.89 (0.59, 1.34) | 0.90 (0.78, 1.05) |
| 1-year all-cause hospitalisation | ||||
| Specialised ILD centre vs. non-specialised centre | 0.93 (0.87, 0.98)* | 0.90 (0.82, 1.00) | 0.94 (0.80, 1.10) | 0.94 (0.86, 1.02) |
| 1-year respiratory-related hospitalisation | ||||
| Specialised ILD centre vs. non-specialised centre | 1.00 (0.92, 1.10) | 0.98 (0.86, 1.12) | 0.89 (0.70, 1.13) | 1.03 (0.90, 1.19) |
CI: Confidence interval, HR: Hazard ratio, IPTW: Inverse probability of treatment weighting
