a

Usual care and SDM toolkit participants were matched on baseline quality of life score, baseline asthma control, age, gender, insurance status, race/ethnicity, and the Charlson comorbidity index. Models were adjusted for variables that were unbalanced after matching.

b

Quality of life score from the Mini Pediatric Quality of Life Questionnaire (MPAQLQ) ranges from 1 to 7; higher score indicates better quality of life

c

Asthma control domain score from the Pediatric Asthma Therapy Questionnaire (PATAQ) ranges from 0 to 7; higher score indicates more control problems

QOL, quality of life; SDM, shared decision making
