Notes. AL source = resident charts; NH source = NH Compare. AL prescribing rates calculated with resident-level weights. p values compare prescribing percentage difference across sites using Wilcoxon signed-rank test (two-sided)

^*One-sample test. Communities matched by ellipsoidal distance based on Vincenty’s equations using coordinates from OpenCage Geocoder.
