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

Background and Aims: The impact of anaesthetic agents on brain relaxation during neurosurgical procedures remains debatable. This study aimed to compare propofol and volatile anaesthetics during maintenance anaesthesia in achieving optimal brain relaxation in adults undergoing intracranial surgery. Methods: We searched PubMed, Embase, Cochrane, and EBSCO Open Dissertations databases from inception to February 2024. Randomised controlled trials (RCTs) comparing anaesthetic agents in patients over 18 years old undergoing neurosurgical procedures were included. The primary outcome was the proportion of subjects who achieved satisfactory brain relaxation, as indicated by a score of 1 on the 4-point Brain Relaxation Score (BRS). The revised Cochrane risk of bias tool was used to evaluate the quality of included studies. Risk ratios (RR) and 95% confidence interval (CI) were calculated using a random-effects model. The effects on brain relaxation were ranked using the surface under the cumulative ranking (SUCRA). We also evaluated the certainty of evidence using the Confidence in Network Meta-Analysis (CINeMA) online platform. Results: Out of 2,264 articles identified, 11 RCTs involving 1,367 participants were included. The chance of having satisfactory brain relaxation of the following anaesthetics appeared to be lower than propofol: sevoflurane (RR: 0.93; 95% CI: 0.79, 1.09), isoflurane (RR: 0.89; 95% CI: 0.60, 1.34), and desflurane (RR: 0.83; 95% CI: 0.65, 1.07), with moderate certainty of evidence. Propofol had the highest SUCRA ranking (81.4%). Conclusion: Although all anaesthetic agents had similar effects, propofol showed a tendency towards better brain relaxation during neurosurgery. Further robust evidence is required to confirm the potential advantages of propofol.
