SF-12 PCS = Short Form-12 Physical Component Scale; higher score reflects better health status
FEV1 % = forced expiratory volume in one second percent predicted
Asthma QoL = Marks asthma-specific quality of life score; higher score reflects poorer QoL
p<0.05
One subject with missing QoL data excluded from analyses for FEV1 and SF-12 as well
