ConsolidatedStandards of Reporting Trials flow diagram showing recruitment of general practices and patients in Check-In. #In the per protocol analyses are only included individuals who responded the questionnaire and who followed the ‘treatment’ for the allocated group (for individuals allocated to intervention, this meant attending the health check and responding to the questionnaire; for individuals allocated to usual care, this meant responding to the questionnaire). Hence, of the 425 responders in the intervention group, 303 individuals attended the health check and could be included in the per protocol analyse. Of the 422 responders in the usual care group, 407 answered the questions regarding the smoking status and could be included in the per protocol analyse.
