Fig. 2From: Reinforcement learning evaluation of treatment policies for patients with hepatitis C virusTreatment probabilities as a function of APRI score for the (a) piecewise treatment policy and (b) logistic regression (APRI only) policy. The first treatment policy is a piecewise function where treatment probability increases with APRI score (a). The second treatment policy is a data-driven treatment policy using logistic regression with APRI as a single feature, and the outcome being a positive diagnosis of cirrhosis (b)Back to article page
