Factors associated with Electrolyte Abnormalities Associated with Refeeding Syndrome on admission

	Hypophosphatemia		Hypomagnesemia		Hypokalemia
	OR (95% CI)	p-value	OR (95% CI)	p-value	OR (95% CI)	p-value
Higher Calorie Refeeding Diet	0.92 (0.24, 3.50)	0.91	0.89 (0.23, 3.43)	0.87	>100 (<0.01, >100)	0.38
%EBW on admit	0.94 (0.88, 1.00)	0.05	0.94 (0.88, 1.00)	0.06	0.04 (<0.01, 36.97)	0.36
Rate of change in calories	1.00 (0.99, 1.01)	0.51	1.00 (0.99, 1.01)	0.56	1.36 (0.73, 2.54)	0.33

Multivariable logistic regression models were used to determine whether level of nutritional rehabilitation on admission was associated with hypophosphatemia, hypomagnesemia, or hypokalemia on the first day of admission. All models controlled for % expected body weight on admission, rate of change in calories, as well as age race/ethnicity, insurance status, diagnosis, and NG/NJ tube status
