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
objectivesThe aim of this study is to examine social functioning as a key domain of obesity-related quality of life (QoL) using the updated MATERIAL AND
methodsThe study was conducted in 2024 among adult patients diagnosed with obesity treated at a hospital dietary clinic in Warsaw, Poland. The study continued the validation work on the OQI-3 instrument following a pilot study. The updated OQI-3 v. 2 consists of 3 sections: 1) gender-adjusted workplace vignettes assessing perceived attitudes and emotions, 2) a multiple-choice list of obesity-affected daily activities, and 3) a 16-item Likert scale assessment of the impact of obesity on daily functioning. Descriptive analyses, item analysis, internal consistency reliability, and principal component analysis (PCA) were performed.
resultsA total of 164 participants were included (125 women and 39 men), with BMI of mean ± standard deviation 40.91±7.68 kg/m², corresponding to class III obesity. The vignette-based section revealed predominantly negative workplace experiences, including discomfort, unfriendly behaviors, and reduced interest, accompanied mainly by emotions such as sadness, stress, frustration, and reduced self-worth. In the daily activities section, rapid fatigability was the most frequently reported difficulty, followed by problems with climbing stairs, poor physical condition, and clothing size issues. The third section demonstrated high internal consistency (Cronbach's α = 0.895). Principal component analysis identified 3 components - interpersonal functioning, self-care, and physical activity - explaining 58.55% of the total variance, each showing satisfactory to very good reliability (α = 0.714-0.877).
