Total Adjusted Effects of Cleft Types on Hospitalization. The graph shows the "total" effects of oral cleft types on hospitalizations days for individuals with oral clefts relative to individuals without clefts. These effects combine the separate effects of cleft types on the probability of hospital admission and on the length of stay when admitted and are estimated from the two-part regression models. The effects 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.
