Comparison of Patient Dose and Exposure Time Across Various Techniques Used to Treat Intracranial Aneurysms : Analysis of the German Neurointerventional Database (DeGIR/DGNR) from 2018 to 2023.

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
purposeThe national diagnostic reference level (DRL) for intracranial aneurysm therapy is set at 20,000 cGy cm
methodsA retrospective analysis of the German DeGIR-QS registry was conducted between 2018 and 2023. This study aimed to investigate the median dose-area product and exposure time for each technique, aneurysm location, type and size. The goal was to ascertain which technique is the most time- and dose-efficient.
resultsFD (84.13%/79.41%) and IaFD (89.64%/73.53%) exhibited superior performance in terms of both effectiveness and efficiency when compared to CE (100% dose-area product/100% exposure time). However, certain aneurysm types and location combinations resulted in lower dose-area product and exposure time when CE was used rather than IaFD or FD. A comparison of the median dose-area product technique with the DRL reveals that all of the aforementioned procedures fall below this value. Aneurysm size has little impact on the finding that FD and IaFD are more efficient in terms of dose and time consumption than CE.
conclusionPatients' exposure can be reduced by selecting a technique associated with lower exposure levels, depending on the aneurysm's location and type. However, conformity is provided for all techniques mentioned.
