Figure B depicts the oriiginal analytic framework of the original comparative effectiveness review by O'Connor and colleagues linking linking the five identified future research needs to specific elements of the population and intervention. Four research questions apply to the population: individuals not responding to usual care, those with anxiety and/or panic disorders, children/adolescents, and those with varying levels of asthma severity. The fifth research question applies to the intervention (use of multi-component asthma interventions including breathing techniques)

* Addressing these research questions would have been included in the original CER, thus, these indicate an evidence gap identified from the CER

Abbreviations: FEV1: forced expiratory volume in 1 second; FVC: forced vital capacity; MV: minute volume; PEF: peak expiratory flow; RQ: research question
