Table 2:

Relationship of race/ethnicity to tracheostomy insertion, adjusting for markers of illness severity

Model A presents odds ratio of tracheostomy insertion by race/ethnicity adjusting for sex, primary insurance, neighborhood median household income, and neighborhood percent of the population with a bachelor’s degree. Model B adjusts for all covariates in Model A, plus gestational age. Model C adjusts for all covariates in Model B, plus the variable indicating non-respiratory major neonatal comorbidities. Model D adjusts for all variables in Model C, plus additional cardiorespiratory comorbidities (pulmonary hypertension, airway abnormality, and congenital heart disease.
