Efficacy of intravenous acetaminophen on postoperative shivering: A meta-analysis of randomized controlled trials.
Synthesis in Medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposePostoperative shivering (POS) is a common and vital complication after anesthesia, which may result in serious consequences and uncomfortable experiences. Acetaminophen has been used to treat fever and mild to moderate pain. However, there is not enough evidence to prove its advantage for POS. This meta-analysis aimed to explore the prophylactic use of acetaminophen as a valid agent for POS.
methodsTwo researchers independently searched PubMed, the Cochrane Library, and Embase for controlled clinical trials. The meta-analysis of randomized controlled trials (RCTs) was performed by Review Manager.
resultsNine trials with 856 patients were included in our meta-analysis. Acetaminophen significantly reduced POS compared with placebo (pooled risk ratio [RR]: 0.43, 95% confidence interval [CI]: 0.35-0.52). What is more, not only 15 mg/kg but also 1000 mg intravenous acetaminophen could reduce the incidence of shivering compared with placebo.
conclusionOur present meta-analysis demonstrates that the intravenous prophylactic infusion of acetaminophen may prevent POS, and the results may provide new evidence to expand the clinical value of acetaminophen in addition to its routine usage.
