Finding F-1297

“No significant associations were observed between O3 concentrations and odds of IVF failure, although there was a slight protective association between higher O3 concentrations between oocyte retrieval and ET and lower likelihood of failure (OR = 0:72, 95% CI: 0.50, 1.04 per IQR increase).”

Structure

Factor: Ozone (O₃)
Population: women undergoing in vitro fertilisation
Setting: city (ambient), US
Study design: prospective cohort of women undergoing in vitro fertilisation at a Boston clinic: time-varying exposure to nitrogen dioxide, fine particulate matter, black carbon and ozone estimated for four windows of each cycle and related to failure of the cycle with logistic regression (class 3)
Effect: OR 0.72 (0.50–1.04) per 1
Caveat: outdoor ozone estimated at the address, not an indoor measurement; the confidence interval crosses one and the text layer prints the odds ratio as 0:72
