Quality of Life, BMI, and Physical Activity in Bariatric Surgery Patients: a Structural Equation Model.
Article in Obesity surgery, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
purposeThe purpose of this study was to use a structural equation model to clarify how physical activity (PA), sex, and BMI relate to quality of life (QoL) of post-bariatric surgery patients.
methodsThe study had a retrospective cohort design for a convenience sample population of 886 bariatric subjects (38 ± 8.49 years). QoL was assessed using World Health Organization Quality of Life-BREF, PA using the International Physical Activity Questionnaire, and BMI values were calculated. Structural equation analysis was conducted in Mplus.
resultsThe physical domain presented positive relationships with BMI (p = 0.014) and the very active group and negative with the insufficiently active A and B groups and sex (p < 0.001). The psychological domain presented negative associations with BMI and the very active group and positive with the insufficiently active A group. The social relations domain presented negative associations with BMI (p < 0.009) and the very active group (p < 0.002) and positive with the insufficiently active A (p < 0.007) and B (p < 0.019) groups. The environmental domain was negatively associated with BMI (p < 0.004) and the very active group (p < 0.001) and positively with the insufficiently active B group (p < 0.049) and sex (p < 0.018).
conclusionBMI is a negative predictor of QoL in bariatric patients and this trend was not observed in the physical domain only; also, the very active group was negatively associated with QoL. We believe that distortions in body weight/body size extend to PA, and research is needed to explore the psychological factors underlying the overestimation of the amount of PA performed.
