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: There is a growing concern regarding the risk of cerebral hyperperfusion syndrome (CHS) associated with simultaneous bilateral carotid artery stenting (SBCAS). This retrospective, single-center, observational cohort study aimed to compare early cerebral hemodynamic changes between patients treated with SBCAS and those treated with unilateral carotid artery stenting (UCAS) through the use of transcranial color-coded Doppler (TCCD). Methods: Data from 25 patients who underwent SBCAS and 165 patients who underwent UCAS between June 2013 and June 2023 were analyzed. TCCD monitoring was conducted for all patients prior to and 1 hour following the carotid artery stenting (CAS) procedure. A propensity score matching (PSM) method was employed to match patients from the SBCAS and UCAS groups in a 1:2 ratio. Key parameters compared between groups included middle cerebral artery peak systolic velocity (MCA-PSV), pulsatility index, blood pressure, and complications. Results: A statistically significant increase in ipsilateral MCA-PSV was detected in both the SBCAS group (35% increase; from 78±25 to 105±22 cm/s; P<0.001) and the UCAS group (27% increase; from 79±23 to 100±28 cm/s; P<0.001). Notably, the increase in ipsilateral MCA-PSV in the SBCAS group was substantially greater than that in the UCAS group (35% Conclusions: The increase in ipsilateral MCA-PSV was significantly greater in the SBCAS group than in the UCAS group. The risk of CHP and CHS was not higher in the SBCAS group as compared to the UCAS group. The use of TCCD post-CAS may be beneficial in monitoring and potentially preventing CHS, particularly in patients undergoing SBCAS, and is therefore recommended.
