Table 4. Health Measures Changes. BMI percentile and FEV1 percent of predicted were collected via chart review at the most recent quarterly in person visit for each participant, both before the study and after completion of all eight weekly prompts. Timing of these visits were thus variable depending on the schedules of each participant. Among all the participants, one participant had BMI < 3 percentile and one participant had BMI >97 percentile, so the values of 3 and 97 were used respectively for calculation. Among participants who completed the study, one participant was healthy enough to skip their FEV1 measurement, so the value was repeated for the after study calculation, and one participant was unable to obtain their FEV1 at the visit so that value was omitted from the calculation.
