2. Figure 1
Odds ratio of live birth with matched and imputed cohort from logistic regression plot. Odds ratio of live birth for multiple covariates in comparison to the reference groups, which are <35 years old for age, male factor for etiology of infertility, 1 for number of embryos transferred, 2004 for reporting year, and Midwest for region. Values are presented as odds ratio with 95% confidence interval. An odds ratio <1 shows that the covariate reduces live birth and >1 shows the covariate increases live birth. *P<.05; **P<.001.

3. Figure 2
Effect of assisted hatching (AH) on the odds ratio of live birth, analyzed by age and reporting year. Data are from a matched and imputed cohort. Values are presented as odds ratio with 95% confidence interval. An odds ratio <1 shows that AH reduces live birth and >1 shows that AH increases live birth. *P<.05; **P<.001.
