Effect of zinc supplementation on quality of life and sleep quality in young women with premenstrual syndrome: a randomized, double-blind, placebo-controlled trial.
Trial report in Archives of gynecology and obstetrics, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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
introductionPremenstrual syndrome is a prevalent disorder affecting a large number of women in their reproductive ages. Nutritional importance of zinc has been known for a long time and studies have shown that zinc can positively affect psychological disorders. PURPOSE: The aim of this study was to evaluate the effects of zinc supplementation on quality of life and sleep quality of young women diagnosed with premenstrual syndrome.
methodsThis randomized, double-blind, placebo-controlled trial was carried out on 60 young university women that were allocated into two groups of intervention who took 30 mg/day of elemental zinc or placebo for three months. Pre- and post-intervention, participants completed the questionnaires of quality of life and Pittsburgh sleep quality.
resultsAfter supplementation, quality of life score in the intervention group was increased (+ 9.185 ± 7.29, P < 0.001), however, in comparison with the control group, results were not significant; Physical aspects of quality of life score were significantly enhanced (+ 5.55 ± 3.71 vs. + 0.13 ± 2.87, P < 0.001). Sleep quality was marginally improved just in the zinc group (- 1.48 ± 4.12, P = 0.07).
conclusionZinc supplementation for 12 weeks had beneficial effects on physical aspects of quality of life in young women with premenstrual syndrome.
