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

aimSuvorexant is an orexin receptor antagonist (ORA) for the treatment of insomnia. The antagonistic action of suvorexant on orexin receptors is associated with an increase in rapid eye movement (REM) sleep, which can potentially lead to nightmares depending on the patient's condition. However, the precise risk factors for nightmares among patients taking ORAs, such as suvorexant, have yet to be identified. In this retrospective study, we aimed to identify the risk factors for the development of nightmares in patients treated with suvorexant.

methodsThe risk factors were determined by comparing parameters between the nightmare group and the nonnightmare group. This study included 440 patients who received suvorexant at the University of Miyazaki Hospital from April 2014 to January 2021.

resultsWe found that 9.1% (n = 40) of the patients experienced suvorexant-induced nightmares. There was a significant difference in the median age, which was lower in the nightmare group than in the nonnightmare group (p < 0.01). Furthermore, both multiple logistic regression analysis and Cox proportional hazards regression analysis revealed increased odds ratios for nightmares for individuals aged 20-39 years.

conclusionsThis study revealed that elderly patients taking suvorexant had fewer nightmares than nonelderly patients did.
