Patient Event Sequencing Study Results II: PRESERVE

*- Seattle consistenly falls below the median in each time bucket, but has more patients that do not have both events than other sites. A similar pattern is observed at UMiami. Given that both of these sites have smaller patient populations than other institutions, the smaller cohort size may be having an impact on these results. - UNC, Stanford, and Lurie have less than the median number of patients without both events. UNC and Lurie trend above the median in every time bucket, while Stanford is only above the median for the 1 year bucket.
