Effects of Decentering on Food Craving in Adults: A Systematic Review and Meta-analysis of Controlled Clinical Trials.
Synthesis in International journal of behavioral medicine, 2025. 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
backgroundFood cravings (FCs) are well-established as a significant factor in obesity. Despite their critical importance, mainstream anti-obesity interventions, including dietary programs and anti-obesity medications, often overlook FCs. While several studies have explored the impact of decentering on FCs, a comprehensive review of this literature has been lacking. Therefore, this study systematically reviewed and analyzed the existing research on the application of decentering to food cravings.
methodWe conducted a systematic review and meta-analysis following PRISMA guidelines and registered it with PROSPERO (CRD420250655903). We systematically searched MEDLINE (via PubMed), Scopus, Embase, CENTRAL, Web of Science, and ProQuest databases. We assessed methodological quality and risk of bias in included studies using the Cochrane RoB2 tool. We evaluated the certainty of the synthesized evidence using GRADEpro. Data synthesis and statistical analyses were performed with CMA v3 software, reporting standardized mean differences as Hedges' g with 95% confidence intervals (CI). To clarify interpretation, outcomes favoring decentering interventions are presented as positive Hedges' g values, while effects favoring control conditions are shown as negative values.
resultsWe identified twelve eligible studies, encompassing 1,079 participants. Across these studies, participants had a mean age of 20.4 years, a mean BMI of 22.8, and were predominantly female (82.8%). Using the RoB2 tool, one study was rated as low risk of bias, seven as having some concerns, and four as high risk. The overall effect size for FC intensity was g = 0.38 (95% CI, 0.16 to 0.59; P = 0.001; n = 11). Using the GRADEpro tool, we rated the certainty of this result as moderate. The pooled effect size for FC frequency was g = 0.12 (95% CI, - 0.28 to 0.52; P = 0.56; n = 6).
conclusionDecentering effectively reduces the intensity of food cravings but not frequency. Because most included studies involved young, normal-BMI women and had short follow-up, the generalizability of our pooled estimates is limited.
