Psychometric Properties of the Iowa Fluoride Study Oral Health Questionnaire in Mexican Adolescents.
Article in Cureus, 2023. 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
BACKGROUND AND
objectiveThe perception of quality of life about health status is subjective; assessment of the impact includes well-being while eating, speaking, smiling, interacting with others, and feeling good about the esthetic appearance of teeth and mouth. The objective of the present study was to cross-culturally adapt and determine the validity and reliability of the Mexican version of the Iowa Fluoride Study Oral Health for adolescents. MATERIAL AND
methodsA cross-sectional study was carried out in a sample of 240 Mexican adolescents aged 15 to 19 years. The questionnaire was translated, back-translated, and administered through the Google Forms platform. The cultural adaptation consisted of the evaluation of the grammatical, conceptual, and linguistic equivalences. The evaluation of the utility and acceptability was carried out through an analysis of semantic equivalence. The utility of the questionnaire was also evaluated by analyzing its grammatical readability. Reliability tests, Kaiser-Meyer-Olkin (KMO), factor analysis, and Pearson's correlation were performed.
resultsThe mean age of all participants was 16.4±1.4; 65.3% (n=158) were female. Face validity was considered adequate. The wording of the objective and instructions of the questionnaire were improved. The confidentiality assurances were highlighted. The questions were clear, understandable, and pertinent, and they showed adequate syntax. The INFLESZ index corresponds to a "fairly easy" level of readability. In the quantitative validation, the correlation of items was greater than 0.4. The KMO was 0.930 (p=0.001), and Bartlett sphericity was 2466.5 (p=0.001). Through the exploratory factorial analysis, we evaluated the emotional well-being (12 items), social welfare (five items), and oral symptoms (OS) (three items) dimensions. Internal consistency was high (Cronbach's α=0.942).
conclusionThe culturally translated and adapted questionnaire is valid and reliable for use in research on Mexican adolescents.
