Multivariable linear regression models were created to examine the relationship between starting on a high calorie nutritional rehabilitation protocol and several outcomes. All models controlled for age of patient, % expected body weight on admission, race/ethnicity, insurance status, diagnosis, and whether an NG/NJ tube was used during the admission. Adjusted estimates with standard errors and p-values are shown for each model
