Recruitment in randomized clinical trials: The MeMeMe experience.

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.
The trial behind it
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
introductionRecruitment is essential for the success of clinical trials. We are conducting a randomized clinical trial to test the effect of a Mediterranean dietary intervention with or without 1700 mg/day of metformin for the prevention of age-related chronic diseases, the MeMeMe trial (Trial registration number: EudraCT number: 2012-005427-32 ClinicalTrials.gov ID: NCT02960711). MeMeMe recruiting experience, highlighting strengths, limitations encountered and results is reported. PATIENTS AND
methodsStatistical analysis focused on the reasons for withdrawal according to the recruitment method ("active" versus "passive" criterion) and the time of withdrawal. Logistic regression models were used to explore the associations between the risk of withdrawal and sex, recruitment method, randomization arm, and with markers of compliance to the intervention, such as one-year change in body weight.
resultsOut of 2035 volunteers, 660 (32.4%) were recruited "actively" and 1375 (67.6%) "passively". Among people who dropped out of the trial after randomization, there were 19.5% for the "active" and 22.0% for the "passive" method (p = 0.28). The risk of withdrawal was significantly higher in women (OR:1.91; 95% CI:1.17-3.12; p = 0.01), in volunteers older at recruitment (OR:1.25; 95% CI:1.07-1.45; p = 0.004), and in those with a higher BMI at baseline (OR:1.23; 95% CI:1.07-1.43; p = 0.004). Volunteers who lost at least 2 kg (the median weight change) in the first year of intervention were significantly less (53%) likely to withdraw from the trial (OR:0.48; 95% CI:0.30-0.75; p = 0.001).
conclusionOur findings suggest that the "passive" recruitment method was more effective than the "active" one to advance recruitment. The benefits of "passive" recruitment hardly outweighed the drawbacks.
