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
Purpose: Transient global amnesia (TGA) manifests as acute short-term memory disturbances lasting up to 24 hours. The pathophysiology of the disease remains unclear. This paper presents the case of a patient with recurrent TGA, in whom a shortening of coagulation times and high blood pressure peaks were observed during each acute phase of the disease, suggesting transient increased blood coagulability and transient dysregulation of autonomic blood pressure control. Case description: A 59-year-old patient with medical history of migraine and arterial hypertension was diagnosed with recurrent TGA (two episodes within a year). Each time, upon admission to hospital, high blood pressure peaks were recorded and activated partial thromboplastin time (aPTT) and prothrombin time (PT) were shortened with gradual normalization over the following days. Comment: The shortening of aPTT and PT may suggest a relationship between TGA and transient blood coagulation disorders in the acute phase.
