This contains planned visits. Not all appointments were kept. Indicator variables show reasons for a missed appointment (if known). This data is not simple. There are more than 1300+ dates duplicated with different visit types. There are week 24 visits that happen at the wrong time (e.g., the date of week 24 is the same as week 8). There are also many cases where two adjacent visits happen on the same day (e.g., both week 7 and week 8 have their visits on the same day). There are both visit and no visit reports on the same day for some people. There are nearly 850 “Cross Active Study” visits and all but 43 happen on the same date as another visit. Many variables have a "1" indicating "Yes". Other are NA because we don't know if those values are real "No" or actually "Unknown". Proceed with great caution.
