Although follow-up evaluations were scheduled 28 and 56 days (four and eight weeks) after surgery, the actual evaluations ranged from 24–46 days after surgery (—X = 32.3, SD = 4.8) for the four-week evaluation and 42–78 days (—X = 57.9, SD = 9.1) for the eight-week evaluation. Differences in the planned and actual dates of data collection were a result of patient noncompliance at the time of the four-week evaluation. The eight-week evaluation was scheduled in conjunction with a doctor’s visit, therefore affecting the desired data collection time.
