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
Purpose: Adenomyosis and endometriosis are both recognized as etiological factors in the development of dysmenorrhea; however, their respective contributions to this condition remains ambiguous. This study aims to examine the distinct contributions of adenomyosis and endometriosis to the symptomatology of dysmenorrhea. Patients and Methods: A total of 480 women undergoing laparoscopy for benign conditions were included, among whom 238 were diagnosed with endometriosis and 236 with adenomyosis. Preoperative assessments of general pain severity of dysmenorrhea and 18 specific menstrual symptoms were conducted utilizing the Visual Analog Scale (VAS) and the COX Menstrual Symptom Scale. Symptom clusters were identified using correlation analyses, hierarchical cluster analysis and graphical least absolute shrinkage and selection operator (GLASSO) network analysis. These clusters were further corroborated by examining the varied correlations between symptoms and VAS scores using Spearman correlation, as well as the distinct patterns of how adenomyosis-related key uterine dimension and endometriosis affected these symptoms through logistic regression analysis. Results: Three distinct clusters of menstrual symptoms were identified. One cluster, which included cramps, nausea, vomiting, loss of appetite, stomachache, and insomnia, demonstrated a close correlation with VAS pain scores. The symptoms within this cluster were influence by common influencing factors, particularly increased uterine anteroposterior diameter and the presence of endometriosis, with a consistent pattern. These characteristics substantiate the classification of these symptoms as the core dysmenorrhea cluster. Although endometriosis exacerbated these symptoms, their severity was not further amplified by higher revised American Society for Reproductive Medicine (rASRM) scores. Conclusion: Menstrual symptoms can be primarily categorized into three distinct clusters, with one cluster potentially representing the core symptoms associated with dysmenorrhea. An increased uterine anteroposterior diameter, probably attributed to adenomyosis, serve as a significant imaging correlate of dysmenorrhea severity, while endometriosis primarily acts to exacerbate them.
