Article in The British journal of general practice : the journal of the Royal College of General Practitioners, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03817255 (Identification of Excessive Substance Use to Encourage Behaviour Change Among Young People in Primary Care), which is not on this map. Cited by 11 papers, 1 of them a synthesis that pooled it.

1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Abstract

backgroundWhen excessive cannabis consumption occurs in adolescence, the adverse consequences extend into adulthood. Interventions by GPs are effective in preventing harm associated with alcohol use. Similar interventions have potential in addressing cannabis use.

aimTo develop and pilot test a brief intervention targeting excessive cannabis use (defined as > or = 1x/week) in young people in primary care. DESIGN OF THE STUDY: Pilot intervention trial.

settingSeven family practices in Switzerland.

methodThe team collaborated with GPs and young people to develop the intervention. Seven GPs piloted its use in their consultations. Patients aged 15 to 24 years consulting for any health problem were recruited before the consultation. Cannabis use, other substance use, and their psychosocial correlates were assessed with a short confidential questionnaire administered before the consultation and 1 month later. GPs, staff, and patients were asked to comment on the study and its feasibility.

resultsOf 81 young people invited to participate, 78 (70% female) agreed (participation rate: 96%). One in seven (13.2%, 95% confidence interval = 7.5% to 18.9%) used cannabis at least once a week. Data at 1 month were available for 42% who had provided email contact details and 91% of those who had provided their mobile phone number (63% overall). In most cases, the intervention lasted no more than 5 minutes. Comments from participants added favourable data towards the feasibility of the study.

conclusionThis pilot study provides a solid base on which to build a randomised trial of a brief intervention addressing cannabis use in young people consulting in family practice.
