Neonatal CSF glucose measured by blood gas analyzer, glucometer, and standard laboratory methods.

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
objectiveTo determine agreement between neonatal cerebrospinal fluid (CSF) glucose measured by standard laboratory method versus blood gas analyzers (BGA) and glucometers. STUDY
designThis prospective, observational, cross-sectional study was conducted in a level III neonatal unit on 97 neonates undergoing lumbar puncture. Agreement was estimated by Lin's coefficient of concordance and Bland-Altman plot.
resultsLin's coefficient of concordance between the CSF laboratory and BGA glucose values was higher than that between CSF laboratory and glucometer glucose {P value < 0.001}. Bland-Altman plot of CSF glucose values by laboratory and BGA methods showed a bias of -0.137 mmol/l. The plot of laboratory versus glucometer methods showed a bias of -0.863 mmol/l. A linear regression equation to predict laboratory CSF glucose from BGA values and glucometer values had an R
conclusionsCSF glucose measured by blood gas analyzers may be used as a point-of-care test among neonates.
