Perioperative management of renin-angiotensin system inhibitors in patients undergoing elective major noncardiac surgery: a mixed model investigation using systematic review, meta-analysis, multicentre service evaluation, and national survey.
Synthesis in British journal of anaesthesia, 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
backgroundThe risks and benefits of stopping or continuing renin-angiotensin system (RAS) inhibitors for major noncardiac surgery remain uncertain. We conducted an updated systematic review, national service evaluation, and clinician survey to inform the design of a large clinical trial of perioperative RAS inhibitor use.
methodsWe searched MEDLINE, CINAHL, ProQuest, Cochrane database, Scopus, and Web of Science from January 2000 to October 2024 for randomised controlled trials (RCT) of perioperative RAS inhibitor use. The primary outcome was a composite of mortality and major cardiovascular events (MACE). Secondary outcomes included acute perioperative hypertension and hypotension. Meta-analysis was performed using random effects models. The I
resultsWe identified five RCTs (n=2848 patients). Stopping RAS inhibitors was not associated with mortality or MACE (odds ratio [OR] 1.21 [0.60-2.42]; P=0.59; I
conclusionsThe optimal approach to perioperative RAS inhibitor use remains uncertain. Although UK clinicians often withhold these drugs, this strategy could cause harm.
