Figure 2.

The associated effect of asthma control during pregnancy after approximately 10 weeks of gestation with risk of preeclampsia controlling for other covariates and plausible confounders derived from criterion based stepwise logistic regression. The model with lowest Bayesian Information Criterion (BIC) was used for construction of the effect plot representing the relationship of uncontrolled asthma month per visit with risk of preeclampsia occurrence (Table 2 and Supplemental Table 1). The solid line demonstrates the point risk estimate and the gray shade its 95% point-wise confidence band. The ticks on horizontal axis represent the subjects with uncontrolled asthma status measured by proportion of uncontrolled asthma months to number of visits in each subject.
