Thirty-six participants finished two-paired calls at all three time points.
Of the possible 225 paired calls (i.e., 75 participants with 3 collection times), 143 two-RA calls were completed within 48 hours, 17 paired calls were removed because they were more than 48 hours apart, and 9 lacked data because the second caller could not reach the participant (see Table 2 for a description of participation).
