The effect of melatonin on quality of sleep in patients with sleep disturbance admitted to post coronary care units: A randomized controlled trial.
Article in BioMedicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
BACKGROUND AND
objectivesPatients with cardiovascular disease who required to be admitted in coronary care units (CCU) would have sleep deprivation. During the admission some factors such as continuous ambient light exposure can suppress melatonin release, in consequence sleep deprivation will be occurred and hinder the progress of patients' treatment. The aim of study was to evaluate the effect of melatonin on the sleep quality of patients admitted to post-CCU. MATERIALS AND
methodsThis randomized clinical trial was carried out on 110 patients admitted to post-CCU at SayyadeShirazi Hospital, Gorgan, Iran. Patients with a poor sleep quality (Pittsburgh sleep quality index (PSQI) global score>5) were randomly allocated into two intervention and placebo groups. Patients in the intervention group received melatonin (3 mg; 30 minutes before bedtime), and the placebo group received placebo for 2 weeks, and their sleep quality was re-evaluated after the end of intervention. Data were analyzed using paired
resultsThe results showed that mean of the patients' PSQI scores decreased significantly in intervention group (from 14.95 ± 1.48 to 11.65 ± 1.50, P < 0.001), while in placebo group the difference was not significant (from 15.48 ± 1.47 to 15.24 ± 1.71, P = 0.129). Post-intervention score of patients in intervention group was also lower than the placebo group (P < 0.001).
conclusionThe melatonin can improve the sleep quality of the patients admitted to post-CCU who suffer from sleep disturbance.
