Fig. 2: Preference score distributions within strata of predicted acute MI risk.

From: A standardized framework for risk-based assessment of treatment effect heterogeneity in observational healthcare databases

Fig. 2

RG-1 represents patients with acute MI risk lower than 1%; RG-2 represents patients with acute MI risk between 1% and 1.5%; RG-3 represents patients with acute MI risk larger than 1.5%. The preference score is a transformation of the propensity score that adjusts for prevalence differences between populations. The percentages in each figure represent the amount of preference score overlap between treatment arms. Higher overlap of the preference score distributions indicates that patients in the target and the comparator cohorts are more similar in terms of the predicted probability of receiving treatment (thiazide or thiazide-like diuretics).
