Effect of calcium on premenstrual syndrome: A double-blind randomized clinical trial.
Article in Obstetrics & gynecology science, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
objectivePremenstrual syndrome (PMS) affects millions of women and is known as the most important disorder among them. The very aim of the present study was to evaluate the effects of low dose calcium on severity of PMS.
methodsThis study can be considered as a double-blind randomized clinical trial. Female students of Hamadan University of Medical Sciences diagnosed with PMS in 2014 participated in the present study. Sixty-six female students diagnosed with PMS were involved in the experimental and control groups. The participants were randomly assigned into two groups to receive 500 mg of calcium daily or placebo for two months. Severity of PMS was detected by Daily Record of Severity of Problems, which was used to measure symptoms during one menstrual cycle before and two menstrual cycles after the intervention.
resultsNo signifcant differences were observed in the mean scores of PMS symptoms between calcium and placebo groups before the treatment (
conclusionOverall, the results of the present study suggest that treatment with calcium supplements is an effective method for reducing mood disorders during PMS.
