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

backgroundThe Attitudes Toward Persons with Obesity (ATOP) scale is widely used to assess stigmatization toward persons with obesity. The measure has previously been suggested to assess three facets-self-esteem, personality, and social difficulties-however, psychometric support for this has been inconsistent and warrants further study if the measure intends to be scored this way.

objectivesExplore and confirm the factor structure of the ATOP in people assessed prior to bariatric surgery and reassessed 1 year postoperatively

settingMidwestern hospital in the USA. MATERIALS AND

methodsThree-hundred sixteen people who were seeking bariatric surgery were assessed preoperatively, and 161 of those people were reassessed 1 year after surgery with a battery of measures including the ATOP. Exploratory factor analysis (EFA) was performed on ATOP data from a random split-half of people before surgery, and confirmatory factor analysis (CFA) was performed on the second randomly selected half. With the postoperative sample, a CFA was performed, testing the best-fitting model from the preoperative CFA findings.

resultsThe EFA suggested a two-factor structure interpreted as self-esteem and personality/social difficulties. This structure was supported by CFA performed on the second randomly selected half of people at preoperative assessment and by CFA performed on people 1 year following surgery. Tests of measurement invariance suggested that the two-factor structure was similar at both time points.

conclusionsOnly two factors for the ATOP were empirically supported in the current sample (self-esteem and personality/social difficulties), which is slightly different from the three factors that were originally proposed when the measure was developed. This factor structure is supported both prior to bariatric surgery and 1 year after bariatric surgery.
