    Worsening Control 155 177 0.26 0.11, 0.41

Status: Good Control= no EPAC for two consecutive visits, where EPAC is defined as ≥30% decrease in PEFR on 2 consecutive days or requirement for rescue bronchodilator usage, urgent care visit, or systemic cortico therapy; Worsened Control= no EPAC prior to first visit, EPAC between first and second visit; Improved Control= EPAC prior to first visit, no EPAC between first and second visit; Continued Poor Control= EPAC before and after first visit in sequence. Differences between categories of control was significant by ANOVA (P<0.0001).
