ID - WHI Participant Common ID Col 2
ADHVTYP - Visit type for HRT adherence period Col 3
ADHVY - Visit year for HRT adherence period Col 4
STARTDY - Days from rand to start of HRT adherence period Col 5 Days from randomization to start of HRT adherence period.
ENDDY - Days from rand to end of HRT adherence period Col 6 Days from randomization to end of HRT adherence period.
ADHRATE - HRT medication adherence rate for the period Col 7 Adherence is a percentage calculated from bottle weight. Values of 1 would indicate 100% adherence. A participant with a value of 5.97 or 597%, for example, would have taken 215 pills in a 36 day period according to the bottle collection information in the database. That would be an entire bottle and probably indicates an error with the data collection. Some possible errors include data entry errors in collection dates or bottle weights, or a bottle collected as empty in error. It could also be that the woman was actually taking more pills than she should have in that time period. You may choose to either throw out values that seem unreasonable or max them out at 100%
COLLECT - Was adherence collection performed during period Col 8 Were HRT pill bottles collected to allow adherence determination for period? If not, no adherence rate can be calculated.
STOPHRT - Participant inactive in HRT interventin during period Col 9 Was the participant inactive in the HRT intervention (i.e. not taking study pills) for all or part of the period.
RESUMEHRT - Participant resumed HRT intervention during period Col 10 Did the participant resume HRT intervention (start taking study pills) during this period after having stopped?
LOST - Participant lost-to-follow-up during period Col 11 Did the participant have a status of lost-to-follow-up during all or part of this HRT adherence period?
DEAD - Participant deceased during period Col 12 Did the participant have a status of deceased during all or part of this HRT adherence period?
OPENLABEL - Were open label HRT meds dispensed during period Col 13 Were any open label HRT medications dispensed to the participant during this period? Usage Notes: Open label medications are not factored into the adherence rate calculation.
ERT2PERT - Participant was switched from E-alone to E+P in period Col 14 Participant was switched from the unopposed estrogen study group to the estrogen+progesterone study group during this period (January 1995), due to PEPI trial results indicating long-term adherence to estrogen was not feasible in women with a uterus.
