LED red light therapy for relief of primary dysmenorrhea: An open, single-group target value clinical trial.
Trial report in PloS one, 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
objectiveTo evaluate the efficacy and safety of LED red light therapy in alleviating primary dysmenorrhea.
methodsA total of 119 patients with primary dysmenorrhea were enrolled in 2022. The intervention was LED red light therapy administered 7 days before menstruation. Clinical outcomes were assessed after three menstrual cycles.
resultsAfter three cycles of treatment, the mean reduction rate in the Visual Analog Scale (VAS) score was 63.62%. The overall effective rate of the device was 98.32%. The total score of the COX Menstrual Symptom Scale decreased by 72.93%, with specific reductions of 72.55% in symptom severity and 73.26% in pain duration. No severe adverse events were reported during the trial. Only one adverse event (0.84%) was considered device-related.
conclusionLED red light therapy is safe and effective for the treatment of primary dysmenorrhea.
