Rehospitalisation risk by hypnotics class in older patients with heart failure: a cohort study utilizing administrative claims data in Japan.
Article in Open heart, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundStudies comparing the safety of orexin receptor antagonists and other hypnotic types for older patients with heart failure (HF) remain lacking. This study aimed to compare orexin receptor antagonists (suvorexant) with benzodiazepines or Z-drugs for sleep treatment and investigate the risk of acute HF-related rehospitalisation in older patients with HF.
methodsThis study used a cohort design to analyse data from an administrative claims database from April 2008 to December 2020. The study population was determined based on inclusion and exclusion criteria from a cohort of 1 159 937 patients aged ≥65 years, selected through random sampling. The follow-up period was censored based on multiple criteria, including outcome occurrences and hypnotic classification changes. Kaplan-Meier survival analysis and Cox proportional hazards models were conducted for risk assessment.
resultsThe analysis included 1858 patients, aged ≥65 years and experiencing their first HF-related hospitalisation. These patients were categorised based on the initially prescribed hypnotic classification, including suvorexant, benzodiazepines and Z-drugs in 490, 606 and 762 patients, respectively. The average age and SD were similar across all hypnotic classes at 82.7±7.6 years. Kaplan-Meier curves indicated a higher trend of rehospitalisation risk for benzodiazepines and Z-drugs than for suvorexant. The adjusted HRs were 2.77 (95% CI 1.17 to 6.52) for benzodiazepines and 2.98 (95% CI 1.33 to 6.68) for Z-drugs.
conclusionsSuvorexant administration for sleep treatment in older patients with HF shows a potentially reduced risk of acute HF-related rehospitalisation compared with benzodiazepines and Z-drugs. The results of this study provide valuable information for selecting hypnotics in older patients with HF having concurrent sleep disorders.
