Behavioral and psychological factors associated with suboptimal weight loss in post-bariatric surgery patients.
Article in Eating and weight disorders : EWD, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 13 papers.
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
purposeBariatric surgery is the most effective long-term treatment for sustained weight loss in obesity. Studies have shown that not all patients lose the expected amount of weight. The aim of this study was to develop a better understanding of which behavioral and psychological factors are associated with suboptimal weight loss.
methodsThe present paper describes a cross-sectional study that included 140 participants. The mean follow-up period after bariatric surgery was 3.16 years. Eating disorder pathology (Eating Disorder Examination-Questionnaire), impulsivity (Barratt Impulsiveness scale-II) and depressive symptoms (Beck Depression Inventory) were compared with successful and suboptimal participants. A weight loss of more than or equal to 50% of excess weight, was considered to be successful.
resultsMore than 81% of the participants met the criterion for successful weight loss. The suboptimal weight loss group reported more symptoms of eating disorder pathology (p = .001), more loss of control over eating (p = .001), and more avoidant behavior due to poor body image (p < .001). The suboptimal weight loss group scored higher on impulsivity (p = .007) and on depression (p < .001). More early weight loss was associated with better weight outcome later on (r = .491). Reporting more eating disorder pathology, a longer follow-up period and pre-operative super-obesity (body mass index ≥ 50 kg/m
conclusionEating disorder pathology, loss of control over eating and avoidant behavior due to poor body image, as well as depressive symptoms and impulsivity, (as reported postoperatively) are associated with suboptimal weight loss. Level III: Case-control analytic study.
