Survey participant eligibility criteria and enrollment

Note: aIn some cases (N=165), contact was not initiated because the target study enrollment was reached prior to placement of the first call to these participants. bParticipants who were unavailable at time of last contact fell into 5 categories: answering machine picked up the call (N=99), call was answered but participant was not home (N=23), call was never answered (N=16), telephone line was busy (N=9), or call was answered by the participant who requested the survey be administered at a later date/time (N=3).
