FIGURE 2.

PARS rescaled strata and High-risk PARS decision rule for the primary drug-based logistic regression model (patient-level 80–20 split stratified by whether a patient had $\ge$ 1 High-risk PARS visit; all visits from a patient confined to a single split. (A) The continuous PARS rescaled score is mapped to qualitative bands on a 0–10 scale: low risk (0–3), moderate risk (3–6), and high risk (6–10). (B) Output of the drug-based logistic model shown as predicted probability of High-risk PARS (defined as PARS $\ge \tau$ 75); the vertical dashed line marks the pre-specified operating threshold of 0.30; visits with $\widehat{p}\ge$ 0.3 are labeled as screen-positive (predicted High-risk PARS = 1, otherwise 0.).
