Figure 2.

Adjusted Effects of Oral Clefts on Hospitalizations. The graph shows the effects of oral clefts on the probability of hospital admission and on the length of stay when admitted for individuals with oral clefts relative to individuals without clefts. Also shown are the "total" effects on hospitalization days that combine both of the aforementioned effects. All effects are estimated from the two-part regression models and are adjusted for all the covariates listed in (Equation 1) for ages 20 years and older and for covariates listed in (Equation 2) for younger ages.
