Adjusted mean differences in systolic blood pressure (mmHg) comparing continuous (natural log transformed) pollution concentrations and stove types among 147 Honduran women using either a traditional or Justa stove*
| 24-hour average air pollution concentrations1 | Adjusted mean difference (mmHg) in systolic blood pressure (95% CI) |
|---|---|
| Personal PM2.5 (μg/m3) (n=104) | 0.8 (−2.2 to 3.8) |
| Kitchen PM2.5 (μg/m3) (n=105) | 2.5 (0.7 to 4.3) |
| Personal BC (μg/m3) (n=105) | 0.5 (−1.0 to 2.0) |
| Kitchen BC (μg/m3) (n=106) | 1.7 (0.3 to 3.0) |

Stove type |
|
| Stove type: Traditional stove (n=74) justa stove (n=72) |
2.8 (−1.1 to 6.6) Reference |
| Stove type: Traditional with use of a secondary stove (n=27) raditional only (n=47) Justa with use of a secondary stove (n=34) justa only (n=38) |
4.2 (−1.8 to 10.2) 2.8 (−2.2 to 7.8) 1.2 (−4.3 to 6.6) Reference |
| Stove type: Traditional only (n=74) Justa installed ≥19 months ago (n=36) Justa installed <19 months ago (n=36) |
