The Influence of demographic variables on the prevalence and severity of tooth wear in a Trinidadian population.
Article in Frontiers in oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: This study aimed to assess the prevalence and severity of wear in a Trinidadian adult patient population based on the demographic variables of age, sex and ethnicity. Methods: Secondary data, stored in an institutional repository as an SPSS file were re-coded. Age was re-coded to stratify the sample into five age groups. A new variable denoting the overall severity of tooth wear was added using the highest score for any examined tooth surface. Data for sex and ethnicity was not re-coded. Likelihood ratios on cross-tabulated data with an alpha level of 0.05 were used to ascertain significant differences in the overall severity of tooth wear for demographic variables. Cross-tabulations were also completed between demographic variables and individual scores for each examined surface in the upper and lower anterior sextants. Results: There was a highly statistically significant association ( Conclusion: Age appears to influence the prevalence and severity of overall wear. The severity of wear on the incisal edges of specific teeth appears to be influenced, in part, by the demographic variables of sex and ethnicity.
