As well as the primary analysis, which compared events over the course of 12 months, we performed post hoc survival analyses that in comparison events in the two groups to 24 months, because the event price at 1 year didn’t reach the anticipated level. For these analyses, data on patient follow-up were censored at 24 months or when the end point occurred. The noninferiority hypothesis was assessed statistically with the use of a z-test, which was based on the 95 percent confidence interval for the total difference in the price of the primary end point at 12 months. Event rates for other end points and 2-year event rates were compared with the use of the log-rank check of time to the first event after randomization.But these records likewise incorporate other identifiers such as date of birth, gender and zip code which can be utilized to re-identify patients, according to the non-profit Electronic Privacy Information Middle . This means that companies can easily search within patients information and obtain deeply private and sensitive info without their consent.
