Clinical features and prognosis of transient global amnesia in Israel: 6 years' single-center experience.

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
backgroundTransient global amnesia (TGA) is a benign neurological syndrome of unknown etiology, causing sudden anterograde amnesia that lasts up to 24 h. During the episode of TGA, other cognitive functions are normal. This is the first study describing the characteristics of the disease in Israel.
methodsA retrospective review of all patients with a confirmed diagnosis of TGA at Shamir Medical Center (SMC) between January 2016 and December 2021.
resultsOne-hundred and four patients with confirmed TGA were identified, with an average age of 64 years (range: 39-87). The annual incidence of TGA was 2.52 per 100,000 and 6.96 per 100,000 among those over 50, with a slight female predominance. The recurrence rate was 11.5%. 61.5% of patients had one or more cerebrovascular risk factors. A precipitating factor was described in 30.8% of cases, with emotional stress, Valsalva maneuver and sexual intercourse being the most prevalent. Chronic ischemic changes were the most common imaging abnormality. Focal slowing was found in nine patients, and epileptic activity was found in four patients.
conclusionsIn this study, we showed that patient characteristics and clinical features of TGA patients in Israel were similar to those described in other reports worldwide. We were unable to demonstrate a specific risk factor or a causative agent. Interestingly, the annual incidence in Israel was lower than in other countries.
