Intravenous dexmedetomidine for delirium prevention in elderly patients following orthopedic surgery: a meta-analysis of randomized controlled trials.
Synthesis in BMC pharmacology & toxicology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
objectivesWe conducted a meta-analysis to investigate the effect of dexmedetomidine on postoperative delirium in elderly orthopedic surgery patients.
methodsA meta-analysis was conducted to identify randomized controlled trials of dexmedetomidine in elderly patients undergoing orthopedic surgery. The data was published on October 25, 2024. PubMed, Embase, and Cochrane Library databases were searched. Outcome measures included incidence of delirium, length of hospital stay, visual analogue scale, and postoperative complications. Estimates are expressed as relative risk (RR) or mean difference (MD) with a 95% confidence interval (CI). The publications were reviewed according to the guidelines of the Cochrane Handbook and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA).
resultsThis study was registered with INPLASY (number INPLASY2024110004). A total of 3159 patients were included in 9 randomized controlled trials. The results showed that dexmedetomidine exhibited a preventive effect on delirium compared with the control group in elderly patients after orthopedic surgery (RR: 0.55, 95% CI: 0.45-0.66, P < 0.01, I
conclusionsDexmedetomidine has been shown to have a protective effect on postoperative delirium in elderly patients following orthopedic surgery.
