Reasons and predictors of non-thrombolysis in patients with acute ischemic stroke admitted within 4.5 h.
Article in Acta neurologica Scandinavica, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05378490 (The Akershus Study of Ischemic Stroke and Thrombolysis -1), which is not on this map. Cited by 6 papers.
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.

Abstract
objectivesThrombolytic treatment in acute ischemic stroke (AIS) reduces stroke-related disability. Nearly 40% of all patients with AIS (<4.5 h) receive thrombolysis, but there is a large variation in the use between hospitals. Little is known about reasons and predictors for not giving thrombolytic treatment. Therefore, we aimed to investigate reasons for non-thrombolysis in patients admitted within 4.5 h.
methodsAll patients with AIS (<4.5 h) admitted to Akershus University Hospital, Norway, between January 2015 and December 2017 were examined. Patient characteristics and reasons for not giving thrombolysis were registered. Descriptive statistics and logistic regression analyses were performed.
resultsOf 535 patients admitted with AIS (<4.5 h), 250 (47%) did not receive thrombolysis and of these only 26% had an absolute contraindication to treatment. Among the 74% with relative contraindications, the most common reasons given were mild and improving symptoms. Previous stroke (OR 3.32, 95%CI 1.99-5.52), arriving between 3 h and 4.5 h after onset (OR 7.76, 95%CI 3.73-16.11) or having mild symptoms (OR 2.33, 95%CI 1.56-3.49) were all significant predictors of not receiving thrombolytic treatment in the multivariable logistic regression model.
conclusionA large proportion of patients with AIS do not receive thrombolysis. This study highlights up-to-date findings that arriving late in the time window, mild symptoms, and previous stroke are strong predictors of non-treatment. It is uncertain whether there is an underuse of thrombolysis in AIS. Increasing the utility of thrombolysis in the 4.5 h time window must be weighed against possible harms.
