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
Objectives: This study aimed to evaluate the agreement between self-reported and clinically measured numbers of teeth in older adults from Almadinah Almunawwarah, KSA, and to identify factors associated with self-reporting accuracy. Methods: This study included 337 older adults (≥60 years). Participants completed a survey assessing sociodemographic characteristics, self-rated oral and general health, and the self-reported number of teeth. Clinical examination was conducted using the 2013 criteria published by the World Health Organization. Bland-Altman plots and correlation coefficients were used to assess the agreement between self-reported and clinically measured teeth. Results: The mean age of the study participants was 67.1 (SD = 6.5) years, and the majority were males (71.2%). The self-reported teeth count was higher than the clinically measured number, and only 47.7% (n = 161) of the sample showed complete agreement between the two measures. The mean difference between the self-reported and clinically recorded number of teeth was 0.41 teeth, and almost two-thirds of the study participants reported their number of teeth within an error margin of two teeth (p < 0.001). Both Spearman's and Pearson's correlation methods revealed a significant positive correlation between the two measures. Specifically, the Spearman's rho was 0.91, while Pearson's r coefficient was 0.96. Conclusion: Among Saudi older adults, the self-reported number of teeth correlated with the clinically measured numbers of teeth. This suggests that self-reports can be a reliable and cost-effective method for assessing oral health in large-scale surveys, potentially guiding health policies and interventions for older adults.
