International Pain Outcomes (IPO) - Brazilian Portuguese version: cross-cultural adaptation and psychometric validation.
Article in Revista brasileira de enfermagem, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesto adapt the International Pain Outcomes questionnaire into Brazilian Portuguese and evaluate its clinimetric properties.
methodswe conducted a methodological, quantitative, validation, and cross-cultural adaptation study of the instrument. The process included translation, synthesis, expert committee review, back-translation, consensus between the English versions and comparison with the original version, pretest phase (n=30), and metric property validation (convergent validity, n=360; interobserver reliability analysis, n=54; internal consistency, n=360).
resultsthe cross-cultural adaptation was successfully performed, and the instrument was considered valid in terms of adequacy and applicability. In the convergent validity analysis, all correlations showed p≤0.001. Cronbach's alpha was 0.796, Kappa was 1.0 (for dichotomous items), and the Intraclass Correlation Coefficient was >0.999 (for quantitative items).
conclusionsthe instrument was deemed adequate for cultural adaptation, validated for Brazilian Portuguese, and reliable for application in the care of postoperative patients.
