| Model | Fuel | |
|---|---|---|
| Clean fuels | Solid fuels | |
| Cox regression, HR for mortality (95%CI) | ||
| Crude, unadjusted model | Ref. | 1.17 (1.10–1.25) |
| Model 1 | Ref. | 1.15 (1.08–1.23) |
| Model 2 | Ref. | 1.10 (1.02–1.18) |
| Model 3 | Ref. | 1.08 (1.009–1.17) |
| Model 4 | Ref. | 1.09 (1.01–1.18) |
| N event | 1,497 | 1,743 |
| Mortality (per 100 person-year) | 9.35 | 9.47 |
Adjustments: Model 1: Sex, age; Model 2: further adjusted residence, smoking, alcohol drinking, dietary diversity score, BMI, marital status, social activity and education; Model 3: further adjusted income, PM 2.5 and city population; Model 4: further adjusted IADL, ADL, MMSE, and chronic disease.
