Game, Set, and Match: A Scoping Review of Matching Characteristics for Control and Intervention Groups in Adaptive Behavioral Interventions for Physical Activity or Healthy Eating Designs for Populations with Overweight and Obesity.
Review in Behavioral medicine (Washington, D.C.), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Behavioral interventions targeting physical activity and/or healthy eating are often used for weight regulation, and adaptive intervention designs that personalize the dosage based on individuals' responses to the intervention components may optimize impact. However, little research has examined how best to design/optimize non-pharmacological adaptive weight regulation trials, and decisions regarding selection/use of control groups in these trials are less clear. This scoping review aimed to identify and describe study and participant characteristics reported and/or used to match intervention and control groups within non-pharmacological, adaptive behavioral weight regulation interventions. Systematic search of adaptive interventions targeting physical activity/healthy eating for weight regulation was conducted following PRISMA-ScR guidelines. Study and participant characteristics reported and/or matched between groups were independently extracted and coded. Of 1,431 articles screened, 4.4% met the inclusion criteria. Study designs were protocol/rationale/design papers (43%), randomized control trials (40%), and pilot/feasibility trials (17%). Most (73%) had a control/comparison condition; 100% matched measurement protocols and dosage exposure. Many (51%) reported participant characteristics (e.g., age, body mass index [BMI]), but only 35% of studies used these as matching factors. Some studies (35%) matched groups on content. These findings illustrate that most adaptive weight control interventions matched the groups based on study characteristics (e.g., measures) but few used participant characteristics (e.g., BMI) despite potential moderating influences on weight regulation. This is an important gap in the literature, and future research is needed to explore the extent to which individual participant characteristics in non-pharmacological adaptive weight control interventions impact dosage efficacy/effectiveness.
