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

objectivesTo systematically examine the prevalence of, and factors associated with, benzodiazepine, Z-drug and melatonin use in Australian residential aged care facilities (RACFs).

methodsMEDLINE, Embase, CINAHL, PsycINFO, Scopus and International Pharmaceutical Abstracts were searched from January 2000 to February 2025 for studies reporting benzodiazepine, Z-drug and/or melatonin prevalence in Australian RACFs. Overall, regular and pro re nata (PRN) medication use was considered. Screening, data extraction and quality assessment were performed independently by two authors. The primary outcome was overall prevalence (regular and PRN) of benzodiazepines, Z-drugs and/or melatonin. Secondary outcomes included regular prevalence, PRN prevalence and medication class prevalence.

resultsFifty-two studies (n = 658,585 residents) were included. Overall prevalence of benzodiazepines and/or Z-drugs was 33% (95% confidence interval [CI]: 30.4%-34.7%, 30 studies) when assessed over periods from point prevalence to one-year prevalence. Prevalence was highest when assessed using prescribing (35%) rather than dispensing (32%) or administration (28%) data. Findings were similar when limited to studies published in the last 10 years (31%), studies of 100 or more residents (32%) and when excluding studies conducted in subsets of residents (33%). Benzodiazepine prevalence (35% [95% CI: 32.5%-36.9%], 24 studies) was higher than Z-drug prevalence (0.4% [95% CI: 0.1%-1.1%], three studies). No published studies reported melatonin prevalence, and unpublished regular prevalence ranged 1%-9% (four studies).

conclusionsOne in three Australian residents in RACFs use benzodiazepines and/or Z-drugs. Targeted interventions are needed to ensure their use is consistent with evidence-based practice and residents' clinical needs.
