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 amyloid angiopathy (CAA) is an age-related condition marked by amyloid-β (Aβ) accumulation in the small cerebral vessels. Iatrogenic cerebral amyloid angiopathy (iCAA) is a distinct form of CAA in younger patients with a history of cranial surgeries involving cadaveric dural transplants. Both iCAA and CAA are linked to recurrent lobar intracerebral hemorrhage (ICH). This article highlights iCAA as a distinct variant, discussing the possibility of using simplified Edinburgh computed tomography (CT) criteria as a possible diagnostic tool for CAA and carefully considering plausible childhood surgery, with the risk of Aβ transmission through dural grafts in all, especially middle-aged patients. Case Description: We present two cases of iCAA in a 46-year-old female and a 52-year-old male who suffered recurrent spontaneous lobar ICHs. The CAA was diagnosed using the simplified Edinburgh CT criteria, leading to further investigations into the underlying pathology. Based on their age, iCAA was suspected, and only after a meticulous search of the hospital documentation it was discovered that they both underwent cranial surgeries in childhood involving cadaveric dural grafts. The diagnosis of iCAA was established using the proposed diagnostic criteria by Banerjee Conclusion: Our paper emphasizes the simplified Edinburgh criteria as a potential yet preliminary diagnostic tool for iCAA, while also highlighting the long-term risks of iatrogenic amyloid transmission related to dural grafting following various neurosurgical procedures.
