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

backgroundCerebrospinal fluid (CSF) spectrophotometry for bilirubin is a highly sensitive test in the diagnostic work up of a suspected subarachnoid hemorrhage (SAH). CASES: We report two cases suffering from an aneurysmal SAH in which extraventricular drainage for acute hydrocephalus was required. Longitudinal analyses of the CSF samples demonstrated that CSF bilirubin was detectable in all cases during the first week, becoming undetectable in one case in the second week. Importantly, CSF ferritin levels rose substantially (>1,000 ng/ml) after 6 days, peaking around 3,000 ng/ml after 2 weeks (normal upper reference range 12 ng/ml). In both cases blood was visible on the initial CT brain scan, disappearing on a later scan.

conclusionCSF ferritin levels may be an important additional laboratory test in the diagnostic work-up of patients with a suspected SAH. CSF ferritin levels may prove particularly helpful in cases with late presentation if the CT brain scan is normal and CSF bilirubin level is undetectable.
