Validation of the Chinese version of the Malocclusion Impact Questionnaire (MIQ).
Article in Clinical oral investigations, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectiveTo translate and cross-culturally adapt the Malocclusion Impact Questionnaire (MIQ) into Chinese and to assess the psychometric properties of the Chinese version of the MIQ (MIQ/C) for use among adolescents with malocclusion in China. MATERIALS AND
methodFirst, the MIQ/C was developed according to international guidelines. Then, the MIQ/C was filled out by 536 adolescents between 10 and 16 years of age. This study used exploratory factor analysis (EFA), confirmatory factor analysis (CFA), convergent validity, internal consistency, and test-retest reliability to evaluate the psychometric properties of the MIQ/C.
resultsFollowing EFA, three domains were extracted, accounting for 65.950% of the total variance. The CFA results showed that the fit indices of each factor in the three-factor model all reached the standard (chi-square/DF = 2.591, GFI = 0.919, TLI = 0.926, CFI = 0.928, RMSEA = 0.076). The scale evidenced a good relationship with the two global questions, indicating good convergent validity. The Cronbach alpha value and the intraclass correlation coefficients (ICC) value of the MIQ/C were 0.929 and 0.893, respectively.
conclusionThe MIQ/C demonstrated good reliability and validity and can be further studied and applied in Chinese adolescents with malocclusion. CLINICAL RELEVANCE: The MIQ/C can be applied to assess the psychosocial impact of malocclusion among Chinese adolescents.
