The Effects of Glasgow Coma Scales and Bispectral Index on General Anaesthesia in Neurosurgery Patients.
Article in Turkish journal of anaesthesiology and reanimation, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveMonitorisation under anaesthesia is important for objective evaluation in intracranial surgery. We investigated general anaesthesia management performed by bispectral index (BIS) monitoring in patients who underwent surgery due to intracranial pathology with different Glasgow Coma Scales (GCS).
methodsForty-five patients who had been planned to undergo intracranial surgery under general anaesthesia were included in the study. Patients were divided into three groups according to GCS: Group I (n ¼ 15) ¼ 13-15 mildly injured; Group II (n ¼ 15) ¼ 9-12 moderately damaged; Group III (n ¼ 15) ¼ 3-8 severely damaged. Heart rate (HR), mean blood pressure, and use of anaesthetic agent were recorded.
resultsIt was found that the consumption of the inhalation agent in Group III was lower than Groups I and II at all time intervals measured, and it was lower in Group II than Group I during the intervals at intraoperative 15th minute and up to 150th minute thereafter. The inhalation agent consumption rates according to the duration of anaesthesia were different between groups. The HR was significantly higher in Group III compared with Group II during the post-operative period. The mean arterial pressure was significantly lower in Group I than Group II preoperatively and at 5th, 10th, 15th, 20th, and 40th minute intra-operatively, whilst it was significantly lower in Group I than Group III preoperatively and 10th minute and 15th minute, intraoperatively.
conclusionWe found that in patients whose GCS was severely damaged and underwent intracranial surgery under general anaesthesia with BIS monitoring, the consumption of inhalation anaesthetic agent decreased, but opioid consumption did not change.
