Receiver operating characteristic curves of an easy-to-use predictive tool using risk scores or simplified risk scores. This predictive tool had a discriminatory capability to determine hospital discharge disposition status at an acute stroke admission. Risk scores were derived from coefficients of multivariable logistic regression related to adjusted odds ratio. Risk scores were further simplified using only 2 positive integers (1 or 2) to represent risks. AUC, area under the curve.
