1 Adjusted for site and allowing for clustering. Eight sites were excluded from the adjusted analysis due to having no adverse events. An additional nine sites were excluded from the adjusted MC method analysis because those sites only conducted surgical procedures. N = 36,534 MC clients included in the age and location adjusted analysis, N = 23,777 MC clients included in the MC method analysis.
