Regression Models for Predictors of Change in Weight at 48 Hours and Net Fluid Loss at 72 hours

Covariate	Change in Weight at 48 hours (N=294)	Net Fluid Loss at 72 hours (N=242)
	P value	P value
Baseline creatinine	NA	.0062
Baseline weight	.36 (+)	NA
Outpatient furosemide dose	94 (+)	Interaction factor
Continuous mode of therapy	.31 (−)	Interaction factor
Continuous mode × outpatient dose	NA	.01
High initial IV diuretic dose	.0002 (−)	.001

The (+) and (−) after the P values signify the directionality of the regression coefficients. NA indicates that the covariate was not tested in the regression model. The number (N) of patients with data available for each regression model is specified. The P values for the interaction factors are not interpretable on their own given their relationship with the interaction term and are not reported.
