Structural Validity and Measurement Invariance of the Scale of Oral Health Outcomes for 5-Year-Old Children.
Article in International journal of paediatric dentistry, 2026. 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
backgroundImportant psychometric approaches (structural validity, measurement invariance) remain underdeveloped in measuring oral health-related quality of life, particularly for preschool children across diverse contexts.
aimThis study aimed to evaluate the structural validity of the child's self-reported version of the Scale of Oral Health Outcomes for 5-year-old children (SOHO-5) and test the measurement invariance from cultural and clinical/non-clinical comparison perspectives.
designThree datasets were analysed: two from Brazil and one from the United Kingdom (UK). One Brazilian dataset was derived from clinical data collection (n
resultsUnidimensionality was empirically confirmed for all three datasets. The multi-group CFA tests reached partial scalar invariance threshold between the Brazilian and UK non-clinical datasets. However, there was no scalar equivalence when comparing non-clinical with clinical datasets, neither within Brazil nor between countries.
conclusionThe child's self-reported version of the SOHO-5 is a unidimensional oral health-related quality-of-life measure that is psychometrically comparable across different cultures (partial scalar invariance), but not between clinical and non-clinical groups.
