Prediction of parenchymal hematoma after mechanical thrombectomy by asymmetrical prominent veins: a retrospective cohort study based on susceptibility-weighted imaging.

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
Background: Asymmetrical prominent veins (APVs) can help predict perfusion deficits and collateral circulation in large vessel occlusion acute ischemic stroke. Therefore, this study aimed to investigate the predictive value of APVs for parenchymal hematoma (PH) following mechanical thrombectomy (MT). Methods: This study retrospectively included consecutive patients with ischemic stroke due to middle cerebral artery occlusion who underwent MT. APVs were quantified using the APVs-Alberta Stroke Program Early Computed Tomography Score (ASPECTS) system, and we recorded the length and diameter of the susceptibility vessel sign (SVS), the number of cerebral microbleeds (CMBs), post-MT blood flow grading, and whether PH occurred within 24 hours. Logistic regression was performed to identify risk factors for PH. Results: A total of 89 patients with acute middle cerebral artery occlusion were included. APVs-ASPECTS was identified as an independent predictor of PH [odds ratio (OR) =0.604 (0.392, 0.930); P=0.022], and the length of SVS [OR =0.882 (0.792, 0.981); P=0.021] was an independent predictor of successful recanalization [modified Thrombolysis In Cerebral Ischemia (mTICI) 2b/3] after MT. There was no significant difference in the number of CMBs between the PH (+) and PH (-) groups (P=0.341). Conclusions: In patients with acute middle cerebral artery occlusion who underwent MT, APVs-ASPECTS may be associated with the risk of PH.
