Cumulative Radiation Exposure Post Aneurysmal Subarachnoid Haemorrhage.
Observational study in Clinical neuroradiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundPatients with aneurysmal subarachnoid haemorrhage (aSAH) often receive multiple radiation based diagnostic studies. Cumulative radiation exposure has been associated with long term health consequences from both dose dependent deterministic harm and increased risk of developing adverse events in a non-dose dependant manner i.e. stochastic harm.
objectiveThe objective was to calculate cumulative radiation exposure in the acute phase after aSAH. DESIGN, SETTING, PARTICIPANTS,
main outcome measuresSingle centre retrospective, observational study of consecutive adult patients admitted to the ICU for management of aSAH over five years. Organ and effective radiation doses were determined using institution specific conversion coefficients based on scanner radiation output metrics for all computed tomography imaging and fluoroscopy examinations. Calculated patient doses for the duration of the hospital admission were determined using National Cancer Institute radiation dosimetry tools.
resultsA total of 276 patients met the inclusion criteria; 180 females (65%), mean (SD) age 56 (13) years. There were 222 (80%) patients who survived to hospital discharge. The median [IQR] effective cumulative radiation dose was 17.7 [9.7-30.5] mSv. Twenty-one patients (8%) received an effective dose > 50 mSV consistent with potentially harmful ionising radiation exposure. In 162 patients (59%), the equivalent radiation dose to the lens of the eye exceeded the 500 mSv threshold for radiation induced damage.
conclusionSurvivors of aSAH are exposed to high levels of medical radiation. The eyes are particularly at risk with most patients exposed to levels known to induce lens damage. This highlights the importance of strategies to reduce incidental and cumulative medical radiation exposure in this population.
