Translation and validation of the OHIP-14 Oral Health Impact Profile into the Quechua language of Peru.

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
The aim of this study was to translate and validate the 14-item Oral Health Impact Profile (OHIP-14) into the Collao variant of the Quechua language for the population of southern Peru. A cross-sectional instrumental study was carried out with 288 participants of both sexes aged between 18 and 65 years (M = 37.53 years; SD = 10.38) who were residents of the department of Cusco, Peru. A convenience sampling method was used. The cultural adaptation process included initial translation, back-translation, review by a committee, focus group evaluation for comprehension and clarity of the items, and a pilot test to ensure the cultural adequacy of the questionnaire. Content validity was evaluated by three evaluators using Aiken's V coefficient. The internal structure was assessed through confirmatory factor analysis (CFA), which tests a three-factor model. The fit indices demonstrated an acceptable model fit, with χ2 = 156.25 (df = 74), RMSEA = 0.062 (90%CI: 0.049-0.076), CFI = 0.999, and TLI = 0.999. The standardized factor loadings exceeded 0.70 for all the items. The corrected item-total correlations indicated strong internal consistency. Reliability was assessed with Cronbach's alpha, which is a high value across all dimensions. The evaluators' assessment demonstrated a high level of agreement for all the items, with Aiken's V coefficient above 0.70. This finding demonstrates that the OHIP-14 is a valid and reliable instrument for the Quechua-speaking population of the Collao variant in Cusco. The study received approval from an ethics committee and adhered to the ethical principles of the Declaration of Helsinki.
