Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote: "Randomization of community pharmacies to control and study group was done by generation of random numbers by computer software."
Allocation concealment (selection bias) Low risk Quote: "Randomization of community pharmacies to control and study group was done by generation of random numbers by computer software."
Baseline outcome measures similar Unclear risk Differences in baseline for education, age and place of residence. Unclear if this was accounted for in the analysis.
Baseline characteristics similar High risk Differences in education, age and residence
Incomplete outcome data (attrition bias) 
 All outcomes High risk Significant number of dropouts from both groups
Blinding of outcome assessment (detection bias) 
 All outcomes High risk No information on blinding
Protection against contamination Low risk Randomisation by pharmacies
Selective reporting (reporting bias) High risk No numerical reporting of quality of life
Other bias High risk High number of control pharmacies withdrew
Blinding of participants and personnel (performance bias) 
 All outcomes High risk No information about blinding provided
