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: Cerebral microbleeds (CMBs) are an important risk factor for stroke recurrence and prognosis. However, there is no consensus on the safety of antiplatelet therapy in patients with ischemic stroke and CMBs. Objective: This study aimed to observe the effects of dual antiplatelet therapy with aspirin and clopidogrel on bleeding conversion in patients with different degrees of CMBs. Materials and Methods: An observational retrospective study was conducted on 160 patients with acute mild ischemic stroke admitted to the Stroke Center, Affiliated Hospital of Beihua University between March 2021 and December 2022. Patients were divided into the CMBs and non-CMB groups. The CMB group was then divided into the low, medium and high-risk groups. In two groups, all patients were administered dual antiplatelet therapy (aspirin 100 mg and clopidogrel 75 mg orally once a day for 21 days according to the Chinese Stroke Guidelines of 2018), and no other anticoagulant or antiplatelet drugs were administered during the treatment period. Head CT, National Institutes of Health Stroke Scale(NIHSS) and modified Rankin Scale (mRS) score were re-checked, and the number of bleeding conversions was calculated at 21 days. Results: Five patients in the CMB group had intracranial hemorrhage (5/116, 4.3%), while no intracranial hemorrhage was observed in the non-CMB group. There were no differences in the conversion rate of cerebral hemorrhage, NIHSS score, or mRS score between two groups after dual antiplatelet therapy ( Conclusion: Dual antiplatelet therapy with aspirin and clopidogrel does not significantly increase the risk of bleeding transformation; however, it improves neurological recovery or long-term prognosis in patients with acute ischemic cerebral stroke complicated by low-risk and middle-risk CMBs.
