Transcranial Doppler After Successful Endovascular Revascularization and Hospitalization Outcomes.

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: Almost half of large-vessel occlusion strokes have unfavorable outcomes despite successful endovascular therapy. We aim to investigate whether postrevascularization cerebral hemodynamics, determined by transcranial Doppler (TCD), associate with hospitalization outcomes in this population. Methods: The current observational cohort study analyzed 155 patients with successfully revascularized anterior circulation large-vessel occlusion stroke (mean age, 68.3±15.4 years; 55% women) who had TCD within 48 hours from endovascular therapy. TCD parameters (mean flow velocity, peak systolic velocity, and pulsatility index) were recorded at the ipsilateral middle cerebral artery, and blood flow signals were categorized using the Thrombolysis in Brain Ischemia grades into normal (grade 5), stenotic (grade 4), or dampened (grade ≤3). Hospitalization outcomes comprised favorable discharge modified Rankin Scale score (0-2), favorable discharge destination (home or acute inpatient rehabilitation), and in-hospital mortality. Logistic regression models adjusted for age, initial National Institutes of Health Stroke Scale score, and Alberta Stroke Program Early CT [Computed Tomography] Score were fit to determine TCD findings in association with study outcomes. Results: Abnormal TCD-derived blood flow was found in 54 (35%) cases, including 35 (23%) with Thrombolysis in Brain Ischemia grade 4 and 19 (12%) with Thrombolysis in Brain Ischemia grade ≤3. Overall, 31% had favorable discharge modified Rankin Scale score, 65% had favorable destination, and 14% died. Thrombolysis in Brain Ischemia grade ≤3 was associated with lower likelihood of both favorable discharge modified Rankin Scale score (adjusted odds ratio [OR], 0.09 [95% CI, 0.01-0.81]) and favorable destination (adjusted OR, 0.22 [95% CI, 0.07-0.71]). Mean flow velocity and peak systolic velocity were not associated with study outcomes. Conversely, increased pulsatility index was inversely associated with favorable destination (adjusted OR, 0.34 [95% CI, 0.13-0.87]). Conclusions: TCD after successful endovascular therapy identified abnormal blood flow in one-third of cases. Dampened flow and markers of increased microvascular resistance were associated with unfavorable hospitalization outcomes. TCD could provide valuable prognostic information in this population and identify potential therapeutic targets.
