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
introductionOral health significantly impacts the quality of life, particularly in vulnerable populations such as children with intellectual disabilities (ID). Existing oral health-related quality of life (OHRQoL) instruments often fail to address the unique challenges faced by these children. This study aimed to develop and validate a novel instrument tailored to assess OHRQoL in intellectually disabled children aged 12-18 years. MATERIALS AND
methodsThe instrument was developed through a comprehensive process involving a literature review and thematic analysis of qualitative interviews with 22 mothers of intellectually disabled adolescents. Content validity was assessed using a panel of five experts from paediatric dentistry, public health dentistry, and research. Content Validity Ratio (CVR) and Content Validity Index (CVI) methods were employed to evaluate individual items and overall scale validity. Items with CVR ≥ 0.99 and I-CVI ≥ 0.78 were retained.
resultsOut of 39 items, 37 achieved a CVR of 1.00, indicating strong consensus on their relevance. The overall S-CVI/UA was 0.864, and S-CVI/Ave was 0.986, reflecting excellent content validity. Two items with CVR scores of 0.2 were excluded. The overall clarity, relevance, and comprehensiveness scores were 2.89, 2.87, and 2.89, respectively.
conclusionThe instrument demonstrates excellent content validity and comprehensively addresses oral health-related quality of life (OHRQoL) challenges in children aged 12-18 years with intellectual disabilities in the Pondicherry City, India. However, considering potential cultural and age-related differences, further studies are warranted to validate its applicability across diverse populations and younger age groups.
