A small change approach to prevent long-term weight gain in adults with overweight and obesity: a randomized controlled trial.
Trial report in CMAJ : Canadian Medical Association journal = journal de l'Association medicale canadienne, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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.

Abstract
backgroundEfforts to manage obesity through weight loss are often unsuccessful as most adults are not able to sustain the major changes in behaviour that are required to maintain weight loss long term. We sought to determine whether small changes in physical activity and diet prevent weight gain in adults with overweight and obesity.
methodsWe randomized 320 sedentary adults with overweight or obesity to monitoring alone (MA,
resultsOverall, 268 participants (83.8%) completed the 2-year intervention, and 239 (74.7%) returned at the end of the follow-up period at 3 years. The difference in body weight change between the SCA and MA groups was significant at 3, 6, 12 and 15 months from baseline, but was no longer significant at 24 months (mean change 0.9 [standard error (SE) 0.5] kg v. -0.4 [SE 0.5] kg; difference -0.6, 95% confidence interval [CI] -1.9 to 0.8) or at 36 months (-1.2 [SE 0.8] v. -0.7 [SE 0.8] kg; difference -0.5, 95% CI -2.2 to 1.2). Changes in waist circumference and cardiorespiratory fitness were not significantly different between groups at 24 or 36 months (both
interpretationThe SCA did not prevent weight gain compared with monitoring alone at 2 or 3 years in adults with overweight or obesity. On average, we observed prevention of weight gain in both arms of the trial.
