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
Objective: This study aimed to cross-culturally adapt and validate the Self-Regulation Questionnaire for Dental Home Care (SRQDHC) for use among Vietnamese children and to examine the relationship between motivation for oral hygiene and dental caries status. Methods: The SRQDHC was translated and culturally adapted for Vietnamese children aged 9-10 years using cross-sectional study. A total of 200 students were randomly selected from a primary school in Hanoi. Clinical dental examinations were conducted to assess caries experience using the dmft and DMFT indices. Subsequently, participants completed the Vietnamese version of the SRQDHC to evaluate their oral hygiene motivation. Internal consistency and factor loadings were analyzed to assess the questionnaire's reliability. Results: Dental caries was observed in 84.5% of participants. The mean dmft and DMFT scores were 3.20 ± 3.18 and 2.15 ± 2.37, respectively. The SRQDHC demonstrated acceptable internal consistency (Cronbach's alpha = 0.7021) and strong factor loadings (>0.3). A statistically significant correlation was found between motivation scores and caries status. Conclusion: The Vietnamese version of the SRQDHC is a reliable tool for assessing dental home care motivation in children. Given the high prevalence of caries in this population, motivation-based oral health interventions are warranted. Further refinement of selected questionnaire items is recommended to enhance its utility in clinical and research settings.
