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

Polycythemia is a condition with abnormal increase in red blood cell mass and number in circulation. Increased attenuation with diffuse involvement of Circle of Willis and cerebral venous sinuses mimicking a contrast enhanced study is one of the early noncontrast CT findings in polycythemia. It can mimic venous sinus thrombosis which is its complication and thus warrants further imaging studies. Further imaging studies are needed for the dense vessel appearance in NCCT where the CT number is above a threshold value.
