Steps taken in calculating the smoking attributable gap, an illustrative example between Taipei City and Tai-tung County (total health disparity gap 9.46 years)
| Smoking related disease category (ICD-9 codes) | Decomposed life years* | Proportion of smoking attributable HDG out of total HDG | SAF from smoking in Taipei City (%) | SAF from smoking in Taitung County (%) | Differences in SAF (%) | SAG (years) |
|---|---|---|---|---|---|---|
| *Decomposed life years from diseases significantly related to smoking in Taiwan within health disparity gap. | ||||||
| †Calculated with the RR of all causes; the value is shown in table 1. | ||||||
| HDG, health disparity gap; ICD, International classification of diseases; MVA, motor vehicle accidents; SAF, smoking attributable fraction; SAG, smoking attributable gap. | ||||||
