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
purposeAlthough orthorexia nervosa, the fixation on health-conscious eating behaviour, was first described in the 90 s, there is no clear understanding whether existing ON measures are appropriate for its assessment. The objectives of the present study were to: (1) examine the psychometric properties of the Polish version of the DOS (PL-DOS) and to compare the PL-DOS with the English version of the DOS (E-DOS) as well as (2) evaluate the prevalence of ON among Polish university students and compare the prevalence rates of ON among Polish and U.S. students.
methodsFour-hundred and twelve students (77.2% female) with a mean age of 24.62 years (SD = 6.86) participated in the present study. All participants completed the Polish version of the Düsseldorf Orthorexia Scale (PL-DOS), the Eating Habits Questionnaire (EHQ) and the Eating Disorder Inventory (EDI).
resultsReliability analysis for the PL-DOS showed strong internal consistency with a Cronbach's alpha coefficient of 0.840 and a coefficient omega of 0.840, 95% CI [0.808, 0.866]. Significant correlation coefficients were found between the PL-DOS and all subscales of the EHQ. Confirmatory factor analysis showed that the one-factor model had poor fit. Polish students had an ON prevalence rate of 6.6%, lower than that of U.S. students (8%).
conclusionsOur findings validate the use of the PL-DOS as an appropriate ON measure for a Polish population. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.
