Bispectral index value correlates with Glasgow Coma Scale in traumatic brain injury patients.
Article in Open access emergency medicine : OAEM, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundAccuracy of consciousness level assessment is very important. It may determine and influence further clinical decisions, thus influences patients' outcomes. The widest method in determining the level of awareness is the Glasgow Coma Scale (GCS). Despite its common use, GCS scores obtained by one clinician may differ from others depending on their interpretations and past experience. One of the tools used to assess the level of consciousness objectively is bispectral index (BIS). The aim of this study was to identify the correlation between BIS and GCS score in patients with traumatic brain injury. PATIENTS AND
methodsA total of 78 patients who were admitted to emergency room for traumatic brain injury were included in this study. One observer evaluated the GCS of all patients to minimize subjectivity. Another investigator then obtained the BIS values for each patient. Spear-man's rank correlation coefficient was used to determine whether GCS correlated with BIS value.
resultsIn 78 patients, the BIS was found to be significantly correlated with GCS (
conclusionIn this study, a significant correlation existed between GCS and BIS. This finding suggests that BIS may be used for assessing GCS in patients with traumatic brain injury. However, the scatters of BIS values for any GCS level may limit the BIS in predicting GCS accurately.
