Efficacy of Plant-Derived Therapies for Primary Dysmenorrhea: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.
Synthesis in Phytotherapy research : PTR, 2026. 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
Primary dysmenorrhea is defined as recurrent, cramp-like lower abdominal pain occurring during menstruation in the absence of underlying pelvic pathology. A significant proportion of the population opts for natural plant-based remedies due to their perceived lower incidence of adverse effects. This study aims to evaluate the efficacy of plant-based interventions in the management of primary dysmenorrhea. Systematic review and meta-analysis. A comprehensive search was conducted across five databases (PubMed, Web of Science, Medline, Embase, and Scopus) covering the period from 1990 to 2025. Randomized controlled trials (RCTs) investigating the efficacy of plant-based products or herbal medicine for the treatment of primary dysmenorrhea were included. Searches, data extraction, and risk of bias assessment were performed independently by two reviewers. Discrepancies were resolved through consultation with a third reviewer expert in the topic. A total of 47 studies were included in the systematic review, of which 22 were incorporated into the meta-analysis. The findings indicate that herbal medicine can be as effective as conventional pharmacological treatments (n = 1133, MD: 0.12, 95% CI: -0.29 to 0.53, p = 0.58, I
