1 · What the graph read from it

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.

2 · The registry

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 BODY-Q is a rigorously developed patient-reported outcome measure (PROM) for patients seeking treatment for obesity and body contouring surgery. A limitation of the uptake of the BODY-Q in weight management treatments is the absence of scales designed to measure eating-specific concerns. We aimed to develop and validate 5 new BODY-Q scales measuring weight loss expectations, eating behaviors, distress, symptoms, and work life. MATERIAL AND

methodsIn phase 1 (qualitative), patient and expert input was used to develop and refine the new BODY-Q scales. In phase 2 (quantitative), the scales were field-tested in bariatric and weight management clinics in the United States (US), The Netherlands, and Denmark between June 2019 and January 2020. Data were also collected in the US and Canada in September 2019 through a crowdworking platform. Rasch measurement theory (RMT) analysis was used for item reduction and to examine reliability and validity.

resultsThe new BODY-Q scales were refined through qualitative input from 17 patients and 20 experts (phase 1) and field-tested in 4004 participants (phase 2). All items showed ordered thresholds and good fit to the Rasch model. The RMT analysis provided evidence of reliability, with PSI values ≥0.72, Cronbach alpha values ≥0.83, and test-retest values ≥0.79. Better scores on 4 scales (exception expectations scale) correlated with lower BMI, with the strongest correlation between the eating-related distress scale scores and BMI (r= -0.249, P < 0.001).

conclusionThe new BODY-Q scales can be used in research and clinical practice to assess weight loss treatments from the patient perspective.
