^∗Total number of facilities in modeling data file in March 2012, N = 426 (114 with intervention); seven facilities were not included in the comparison because of a low number of eligible residents (<10 residents). Data are means of facility-level resident counts and prevalence data rather than a summary of individual-level data.
