1 · What the graph read from it

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.

2 · The registry

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

To investigate the efficacy of exogenous administration of melatonin and melatonin receptor agonists for the improvement of delirium, sleep, and other clinical outcomes of subjects in the intensive care unit (ICU). We carefully searched three electronic databases, i.e., Pubmed/Medline, Embase, and Cochrane library, to retrieve randomized controlled trials (RCTs) administrating melatonin or melatonin receptor agonists to adult subjects admitted to the ICU. Useful data such as the prevalence of delirium, duration of sleep, number of awakenings per night, duration of mechanical ventilation, and ICU stay as well as in-ICU mortality were extracted and pooled by using a random effect model. Eight RCTs were included in the qualitative analysis. Administration of exogenous melatonin and melatonin receptor agonists was associated with a trend towards elongated duration of sleep (pooled weighted mean difference/WMD = 0.43; 95% confidence intervals/CIs, - 0.02~0.88, p = 0.063) and could decrease the number of awakenings per night (pooled WMD = - 2.03; 95% CIs, - 3.83~- 0.22, p = 0.028). Meanwhile, participants in the treatment group showed a significantly reduced prevalence of delirium (pooled risk ratio/RR = 0.49; 95% CIs, 0.28~0.88, p = 0.017) and duration of ICU stay (pooled WMD = - 0.32; 95% CI, - 0.56~- 0.07, p = 0.002) in comparison with those in the control group. Exogenous administration of melatonin and melatonin receptor agonists could improve the sleep of subjects in the intensive care units, which may play an important role in decreasing the prevalence of delirium and shortening duration of ICU stay.
