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
Background: Dysmenorrhea is chronic and cyclic pain during menstruation and is a common gynecological problem worldwide. Although there are several reported risk factors for dysmenorrhea, the findings of previous studies are inconsistent. This study aimed to identify lifestyle factors associated with dysmenorrhea. Methods: The study population comprised 36,665 premenopausal female nurses aged 20-49 years who completed the Japan Nurses' Health Study (JNHS) baseline survey. Out of grades 0-4 of menstrual pain, dysmenorrhea was defined as grades 2-4. Multivariable modified Poisson regression analysis was used to examine the associations between dysmenorrhea and possible risk factors, namely age, current menstrual cycle, marital status, parity, current body mass index (BMI), smoking status, alcohol consumption, work shift, physical activity, sleep duration, and soybean isoflavone intake. Results: There was a significant negative association between age and the prevalence ratio (PR) of dysmenorrhea ( Conclusion: The JNHS baseline survey revealed that the factors associated with dysmenorrhea in Japanese women were age, parity, menstrual cycle, being underweight, and lifestyle factors, including soybean food intake.
