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

backgroundThe presence of the spot sign on computed tomography angiogram (CTA) is considered a sign of active bleeding, and studies have shown it can predict hematoma expansion in intraparenchymal hemorrhage (IPH). The spot sign in intraventricular hemorrhage (IVH) has not been explored yet. The purpose of this study is to estimate the prevalence of the intraventricular-spot sign, and its prediction of hematoma expansion and clinical outcomes.

methodsWe retrieved data of hemorrhagic stroke patients seen at our medical center from January 2013 to January 2018. A total of 321 subjects were filtered for the prevalence analysis (PA). We further excluded 114 subjects without a follow-up CT-head for the hematoma expansion analysis (HEA). Patients were grouped based on the location of hemorrhage into three groups: isolated IPH with the spot sign always in IPH (i-IPH), isolated IVH with the spot sign always in IVH (i-IVH), and combined IPH and IVH which would be further sub-grouped according to the location of the spot sign: in IPH only (IPH+/IVH) and in IVH only (IPH/IVH+). The prevalence, demographics, and incidence of hematoma expansion were compared between the groups using Pearson's chi-square test and Student's t test.

resultsThe prevalence of the spot sign was 8, 20, 17, 5% in (i-IPH), (i-IVH), (IPH+/IVH), and (IPH/IVH+) groups, respectively. The rate of hematoma expansion were (42 vs. 13%), (33 vs. 31%), (80 vs. 22%), and (25 vs. 22%) in spot sign positive vs. negative subjects in each group, respectively (p values = 0.023, = 1, <0.001, and = 1).

conclusionWe studied the prediction of spot sign on hematoma expansion and clinical outcomes in the different subtypes of ICH. Our study showed that spot sign is a good predictor in IPH but not IVH. Despite the rarity of IVH; the prevalence of spot sign was higher in IVH than IPH. This might be due to anatomical and physiological variations.
