Average carbon monoxide (CO) exposures during Randomised Exposure Study of Pollution Indoors and Respiratory Effects (RESPIRE) and Childhood Exposure to Respirable Particulate Matter (CRECER) by study group*
| Group 1, mean (SD) | Group 2, mean (SD) | Group 3, mean (SD) | p Value | |
|---|---|---|---|---|
| Average RESPIRE CO† (ppm) | 1.18 (0.5) | 1.97 (0.8) | 1.66 (0.8) | <0.0001 |
| Average CRECER CO (ppm) | 0.88 (0.7) | 0.88 (0.5) | 1.28 (0.6) | <0.0001 |
*Shaded boxes indicate measurements taken with stove in place. Unshaded boxes indicate measurements taken prior to stove installation.
†For Group 3 only, the study child's early life exposures were estimated based on CO measurements of their infant sibling, collected prior to stove installation during CRECER in the first 18 months of life.
