A. Time from randomization to data collection by treatment group. All patients had first data collection at time of randomization (week 0), and following collections were to begin at weeks 12, 24, 36 and 48, corresponding to 3, 6, 9 and 12 months (vertical dotted lines). Numerals 1, 2, 3 and 4 indicate the collection number and the timing, in weeks, of those collections. PT=portal training, PT+HV=home visit plus portal training.
B. Time from randomization to home visits. Anticipated home visit times at start of study were at 3, 5, 8 and 25 weeks, with ranges of a few weeks before and after (vertical dotted lines). Numerals 1, 2, 3 and 4 indicate the visit number, and the weeks on the x-axis correspond to the actual visit times in weeks from randomization. A patient could have fewer than 4 home visits. If the last visit was also the second visit, then the patient would have only a "1" and a "2" in this figure; "3"' and "4" would be missing.
