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
purposeDigital subtraction angiography (DSA) is the gold standard for follow-up evaluation of intracranial aneurysms treated with the Woven EndoBridge (WEB) device. This study aimed to assess the efficacy of high-resolution CT angiography (HR-CTA) as a less invasive alternative by comparing its diagnostic performance with that of DSA.
methodsThis single-center retrospective study analyzed the angiographic and clinical data of patients treated with the WEB device for cerebral aneurysms between January 2021 and December 2024. Patients who underwent HR-CTA within 2 weeks before or after follow-up DSA were included. Occlusion status was assessed using the Bicêtre Occlusion Scale Score (BOSS) and binary classification. The concordance rate between HR-CTA and DSA was evaluated.
resultsA total of 54 eligible examinations were identified. Using the BOSS, 46 examinations were concordant, resulting in an agreement rate of 85.2%. The Cohen's κ coefficient was 0.81 (95% CI 0.69 to 0.93), indicating a very high level of agreement. All discordant cases resulted from HR-CTA overestimating occlusion status; however, HR-CTA accurately identified aneurysm remnants. Univariate analyses identified BOSS 0' as the only significant factor contributing to discrepancies. In the binary evaluation, all 54 examinations were fully concordant (κ=1.00, 95% CI 1.00 to 1.00).
conclusionsHR-CTA demonstrated a high concordance rate with DSA for evaluating occlusion status after WEB placement. Its reliable assessment of aneurysm remnants suggests HR-CTA could serve as a practical and less invasive alternative to DSA in follow-up evaluations.
