  1. Performance of the RCP3Q to detect uncontrolled (UC) and well-controlled (WC) asthma in children as defined by C-ACT (age 5–11) or ACT (age 12–16) score. The population aged 5–11 included the 223 children completing the C-ACT. The population aged 12–16 included the 96 children completing the ACT
