A number of trials which were gathered inside was in fact noticed valid having introduction regarding analytical analyses. Trying to find appropriate healthcare experts permanently living/in for every single section-so you can optimize the fresh new response rate-became extremely tough, and therefore lengthened enough time wanted to complete the fieldwork past the prepared big date.

Participants
