Clinical Outcomes
Between baseline and exit visits, the percentage
of study group children whose asthma
was either not well controlled or very poorly
controlled significantly improved, from 100%
to 28.8% (P < .001; Table 3). The comparison
group also had a significant improvement,
from 100% to 51.6% (P < .001); however, the
study group’s absolute percentage reduction
was significantly greater than that of the comparison
group (P = .04). Moreover, the study
group’s improvement in caregivers’ quality of
life exceeded that observed for comparison
group caregivers (P = .002) by 0.7 units, a
clinically important difference.
