Overtreatment and undertreatment rates measured at facilities by year and threshold. For all three overtreatment thresholds, a decrease over time was observed. The rates of overtreatment increase with the overtreatment threshold as more patients are captured. The undertreatment rates are of similar magnitude to the overtreatment rates using 6% as the threshold and are increasing over time. Outliers are more present at high rates than at low rates
