1 · What the graph read from it

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.

2 · The registry

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

Introduction Magnet Resonance Imaging (MRI) is essential for neurocritical care but requires intrahospital transport (IHT) in patients treated in an intensive care unit, which carries significant risks. This study assesses the risk profile and whether the benefits of MRI in aneurysmal subarachnoid hemorrhage (aSAH) outweigh the associated complications of IHT. Method In this retrospective study, all aSAH patients treated in our neurocritical care unit (NCCU) between 2016 and 2023 were screened. Data collection included baseline demographics, hemorrhage severity scores, aneurysm treatment strategies, additional neurosurgical procedures, and need for spasmolysis. IHT- and MRI-related variables were recorded, including timing, indication, duration, and associated physiological parameters such as blood gas values, vital signs, intracranial pressure (ICP), and cerebral perfusion pressure (CPP). The incidence of complications and the clinical impact of MRI findings were evaluated. Statistical comparisons were conducted using the Wilcoxon signed-rank test. Results Of 337 screened patients, 115 (34.1%) patients with aSAH underwent a MRI during the NCCU stay and were included in the analysis, with a total of 156 MRI scans performed. The most common reason for a MRI was ischemia exclusion (61%). Complications occurred in 16% of patients (n = 25), classified as systemic (56%), cerebral (37%), and technical (7%). Blood gas analysis showed no significant changes before and after IHT. In the subgroup of patients with an external ventricular drain (EVD) in situ (n = 93), ICP remained stable, while CPP increased from 85.4 (± 20.5) to 92.1 (± 19.9) mmHg (p = 0.009). Accordingly, systolic BP and MAP increased (p = 0.019 and < 0.001, respectively) and HR decreased by 4/min (p < 0.001). Conclusion We found lower frequency of IHT-related complication in brain MRI after aSAH compared to existing literature reflecting a well-established and safe clinical process. Moreover, MRI findings had a notable impact on key therapeutic decisions, supporting the use of MRI-based IHT in selected cases, provided that a thorough risk-benefit assessment is conducted.
