Prevalence of irregular menstruation according to socioeconomic status: A population-based nationwide cross-sectional study.
Trial report in PloS one, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 44 papers, 4 of them syntheses that pooled 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.
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
Irregular menstruation is an important indicator of current and potential health problems. A woman's health is greatly influenced by her socioeconomic status. The purpose of this study was to examine the prevalence of irregular menstruation by socioeconomic status among South Korean women. Secondary data analyses were conducted among 4,709 women, aged 19-54 years, using raw data from the Korea National Health and Nutrition Examination Survey V (2010-2012), a nationally representative survey. Compared to women who graduated from university, the adjusted odds ratios (95% confidence intervals) for those who graduated from elementary school or lower, middle school, and high school were 3.256 (1.969-5.385), 2.857 (1.866-4.376), and 1.607 (1.261-2.048), respectively. Compared to women with a medium-high income level, the adjusted odds ratio (95% confidence interval) for women with the highest household income level was 1.409 (1.091-1.819). Irregular menstruation was prevalent among adult women and appeared to be associated with socioeconomic status, especially in terms of education and household income. This study's findings suggest that attention must be paid to women with low educational levels or high household incomes, to ensure early diagnosis and the provision of medical attention for irregular menstruation.
