1 · What the graph read from it

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.

2 · The registry

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

backgroundConsidering that the association between socioeconomic status (SES) and oral health status differs by sex, we examined the impact of factors such as education, economic status, employment type, and social support on tooth loss in dental patients attending clinics, separately for men and women.

methodsThis study was based on a survey of dental patients across Japan conducted by the Foundation for the Promotion of 8020 between 2014 and 2019. To determine sex differences in the association between number of teeth lost and SES, a modified Poisson regression analysis was performed with the number of lost teeth during 5 years as the dependent variable. The ratio of means (RM) was calculated separately for men and women.

resultsIn total, 1,355 participants were included in the analysis. Among women, those with fewer years of education or temporary employment had a significantly higher RM for tooth loss. Moreover, women with a higher subjective economic status or more social support had a lower RM for tooth loss. In contrast, there was no significant association between SES and tooth loss among men.

conclusionsThe association between tooth loss and SES differs by sex. Preventive strategies should consider SES-related sex differences in oral health.
