‚ÄÉMean odds ratios (95% confidence intervals) for associations between smoking exposures and each outcome

OutcomeExposure to:
Current smokingSmoking in pregnancySmoking in first 2 years
Confounder adjustedFully adjustedConfounder adjustedFully adjustedConfounder adjustedFully adjusted
*p<0.05 **p<0.01.
Differences between estimates from the two models may include the loss of up to two studies when adjusting for smoking during the first two years of life.
HHeterogeneity between study specific results (p<0.10).
Odds ratios are from confounder adjusted models, and from fully adjusted (for previous covariates plus both other smoking variables).
