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

Supratentorial superficial siderosis (SS) is a frequent imaging marker of cerebral amyloid angiopathy (CAA). It is most probably caused by focal subarachnoid hemorrhages (fSAHs). Based on single-case observations, it has been proposed that such fSAHs might be a predisposing factor for future intracranial hemorrhage. Here we tested the hypothesis if a SS as a residue of fSAHs must be regarded as a warning sign for future intracranial hemorrhage. Fifty-one consecutive patients with SS and no apparent cause other than possible or probable CAA were identified through a database search and followed-up for a median interval of 35.3 months (range 6-120 months). Main outcome measures were rate and location of new intracranial hemorrhages. Twenty-four patients (47.1 %) had experienced any new intracranial hemorrhage, 18 patients (35.3 %) had an intracerebral hemorrhage (ICH), and in 13 of them (25.5 %), the hemorrhage was located at the site of pre-existing siderosis. Six patients (11.7 %) had developed a new subarachnoid hemorrhage (SAH), four of them at the site of siderosis. Patients with SS are at substantial risk for subsequent intracranial hemorrhage. SS can be considered a warning sign of future ICH or SAH, which frequently occur adjacent to pre-existing SS. Prospective studies are needed to confirm these findings.
