Clinical significance of post-interventional cerebral hyperdensities after endovascular mechanical thrombectomy in acute ischaemic stroke.

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
introductionThis study aims to investigate the clinical significance of post-interventional cerebral hyperdensities (PCHD) after endovascular mechanical thrombectomy in acute ischaemic stroke.
methodsData of 102 consecutive patients who received post-interventional CT scans within 4.5 h after mechanical thrombectomy were analysed retrospectively.
resultsSixty-two of 102 patients (60.8 %) had PCHD on their post-interventional CT scans. The most common site of PCHD was the basal ganglia. PCHD were persisting in 13 of 62 patients (21.0 %), and transient in the remaining 49 patients (79.0 %) within 24 h. Four patients with PCHD and four patients without PCHD suffered from parenchymal haemorrhage. Neither ASA nor Clopidogrel, Tirofiban or rtPA were risk factors for PCHD. Final infarction size was congruent with or bigger than areas of PCHD in 93.3 % of cases in our series.
conclusionPCHD was not a risk factor for parenchymal haemorrhage in our series. The occurrence of PCHD was strongly related to the prior presence of infarction. PCHD was also a strong predictor for final infarction size.
