Effect of vitamin D and E supplementation on pain relief and premenstrual symptoms in primary dysmenorrhea: a randomized controlled trial.

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
introductionPrimary dysmenorrhea is a common condition characterized by painful menstrual cramps. Vitamin D and E are suggested to have potential benefits in managing dysmenorrhea. This study aimed to investigate the effects of vitamin D and E supplements combination on pain intensity and premenstrual symptoms in individuals with primary dysmenorrhea.
methodsA double blinded randomized controlled trial was conducted with 106 participants diagnosed with primary dysmenorrhea. The participants were randomly assigned to either the intervention group (received vitamin D and E supplements) or the control group (received placebo). Pain intensity and premenstrual symptoms were assessed at baseline and after four months of supplementation.
resultsThe intervention group exhibited a significant reduction in pain intensity (NPRS: from 7.85 ± 1.15 to 3.75 ± 1.40; mean difference - 4.10, 95% CI: -4.61 to -3.58, p < 0.001) compared to controls (7.68 ± 1.20 to 6.02 ± 1.70). Premenstrual symptoms significantly improved (PMS score: 32.42 ± 4.67 to 9.02 ± 8.84, Δ=-23.40, 95% CI: -26.51 to -21.02, p < 0.001). Baseline vitamin D inversely correlated with pain (r=-0.768, p = 0.001).
conclusionCombined vitamin D and E supplementation significantly reduces pain and PMS in vitamin D-deficient women. Healthcare providers may consider this regimen for dysmenorrhea management, pending further optimization studies.
