Barbanel 2003.

Methods	Randomised controlled trial
Participants	24 adults from a socioeconomically deprived, ethnically mixed area in the United Kingdom (Tower Hamlets in London) with GP diagnosed asthma
Interventions	Following attendance at a 3‐day training course on asthma care at the London Chest Hospital, a number of pharmacists were allocated a group of adults to educate. The pharmacists then delivered an educational session on asthma topics and reviewed inhaler technique, and use of a Peak Expiratory Flow Meter, taking a minimum of 45 minutes. They gave the patients supporting literature and a self‐management plan. The pharmacists then phoned the participants on a weekly basis for 3 months in order to give encouragement, answer questions and encourage patients to return to the pharmacy with any problems. The control group received no input from the pharmacist
Outcomes	Primary outcome measure was asthma symptoms as measured using the North of England Asthma Symptoms Scale completed at baseline and 3 months after intervention

Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	“Subjects were randomised to intervention or control groups”

Blinding (performance bias and detection bias) All outcomes	High risk	Unable to blind participants from intervention or control
Incomplete outcome data (attrition bias) All outcomes	Low risk	One participant moved away and their data were imputed using appropriate methods
Selective reporting (reporting bias)	Low risk	No evidence of selective reporting
Other bias	Low risk	No evidence of other bias
