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
Introduction The psychosocial impact of dental aesthetics significantly influences adolescents' emotional well-being, self-esteem, and social interactions. While the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) has been validated across diverse populations, no version previously existed for the Odia-speaking adolescent population in Eastern India. This study aimed to translate, culturally adapt, and validate the PIDAQ for adolescents aged 10 to 13 years in Odisha. Method The original PIDAQ was translated and culturally adapted into Odia following forward and backward translation, expert panel review, and pilot testing. The finalized questionnaire was administered to 450 adolescents from urban and semi-urban schools in Odisha. Internal consistency was evaluated using Cronbach's alpha, and test-retest reliability was assessed with intraclass correlation coefficients (ICC). Construct validity was determined through exploratory factor analysis, and discriminant validity was established by comparing scores across malocclusion severity categories using the Index of Orthodontic Treatment Need-Dental Health Component (IOTN-DHC) and Index of Orthodontic Treatment Need-Aesthetic Component (IOTN-AC) indices. Convergent validity was evaluated by correlating PIDAQ scores with IOTN-AC scores. Results The Odia version of the PIDAQ demonstrated good internal consistency, with Cronbach's alpha values ranging from 0.72 to 0.78, and high test-retest reliability (ICC ranging from 0.71 to 0.84). Exploratory factor analysis confirmed a stable four-factor structure explaining 56.56% of the total variance. Discriminant validity was demonstrated through significant differences (p < 0.001) in PIDAQ scores across malocclusion severity groups. Moderate, statistically significant correlations between PIDAQ scores and IOTN-AC scores (ρ = 0.389) confirmed convergent validity. Conclusion The Odia-adapted PIDAQ is a reliable, valid, and culturally appropriate tool for assessing the psychosocial impact of dental aesthetics in adolescents, with significant potential for clinical use, public health research, and policy development.
