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
objectivesThis study aimed to evaluate the association between malocclusion severity and oral health-related quality of life (OHRQoL) in children aged 11-14 years by simultaneously using the Child Perceptions Questionnaire (CPQ11-14), Parent/Caregiver Perceptions Questionnaire (P-CPQ), and Dental Aesthetic Index (DAI). MATERIAL AND
methodsThis analytical cross-sectional, clinic-based study was conducted on 117 children aged 11-14 years and their parents/guardians referred to a specialized dental clinic in Rasht city, Iran, in 2022. Children with systemic diseases, a history of orthodontic treatment, or craniofacial abnormalities were excluded. OHRQoL was independently assessed using the CPQ11-14 and P-CPQ. Malocclusion severity was determined using the DAI, and children were categorized into normal occlusion, definite, severe, and very severe malocclusion groups. The associations of age and gender with OHRQoL were also examined. Data were analyzed statistically (α = 0.05).
resultsThe mean OHRQoL score was significantly higher among children with malocclusion compared with those with normal occlusion (p < 0.001), indicating poorer quality of life. Higher malocclusion severity was significantly associated with worse OHRQoL scores (p < 0.001). These associations were significant in both sexes (p < 0.05). A significant association between malocclusion severity and poorer OHRQoL was observed in children older than 12 years (p < 0.001), whereas this association was not statistically significant in children aged 12 years or younger (p > 0.05). Multivariable analysis confirmed that malocclusion severity remained independently associated with OHRQoL after adjustment for demographic factors (p < 0.001).
conclusionsGreater severity of malocclusion, particularly in older children, is significantly associated with poorer OHRQoL. The relative agreement between child and parent assessments highlights the importance of considering both perspectives in clinical and research settings.
