Psychometric properties of the ORTO-R in a community-based sample of women and men from Poland.
Article in Journal of eating disorders, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
purposeOver the past two decades, orthorexia nervosa (ON) has been increasingly investigated. Recently, a new revision version of the ORTO-15, namely ORTO-R, was used. The main objective of the present study was to confirm the factor structure of Polish version of the ORTO-R for evaluating ON thoughts and behaviors.
methodIn three studies, a total of 3081 participants was selected by random sampling through several universities and companies. In Study 1, we used original items of ORTO-15, in Study 2 we used both, the ORTO-15 items and the revised items from ORTO-R, and in Study 3 we used only the items from the ORTO-R. Confirmatory factor analysis was used for determining the factorial structure of the Polish version of the ORTO-R. We also assessed internal consistency and convergent and criterion validity of the ORTO-R.
resultsThe model composed of the revised items (ORTO-R) was characterized of good convergent and criterion validity. Furthermore, ORTO-R appeared to be more internally consistent as compared to ORTO-15.
conclusionThe 6-item ORTO-R is valid and reliable method to assess orthorexic thoughts and behaviors among Polish-speaking population and could be applied in future research. Using revised version of the items is strongly preferred to using the items in their original ORTO-15 form.
