^∗P value for Kruskall-Wallis test of difference in median number of gaps. Blank cells indicate value > .05.

^†Pairwise comparisons adjusted for multiple comparisons show significant difference between facilities with 4-star and 1-star quality ratings (P = .029) and with 4-star and 2-star quality ratings (P = .026).

^‡Ownership categories sum to 627 facilities. Two nongovernment-owned facilities that provide skilled nursing care but were not in CMS data sets were excluded from analysis by ownership type.
