Portable Bedside Low-Field MRI for Assessment of Ventricular Size.
Article in AJNR. American journal of neuroradiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
background and purposeLow-field portable MRI (pMRI) has been shown to be a useful alternative neuroimaging tool in the emergency department (ED) and intensive care unit (ICU), potentially addressing challenges associated with the transport of critically ill patients. We aimed to evaluate the intermodality reliability between low-field pMRI and conventional neuroimaging (CN) for assessment of ventricular size and hydrocephalus. MATERIALS AND
methodsThis retrospective study included all patients who underwent point-of-care 64 mT pMRI at a single tertiary hospital from March 30, 2022 to January 4, 2024, and had a follow-up CN, either CT or MRI, performed within 24 hours of the pMRI scan. Two raters independently evaluated pMRI for presence of hydrocephalus while blinded to CN. Bifrontal diameter, maximum skull, and Evans index were recorded. Interrater and intermodality agreement between pMRI and CN were evaluated by using the intraclass coefficient (ICC) and Cohen κ.
resultsFifty-six patients (mean age of 53.5 [±14.6] years, 61% men) were included in this study. Hydrocephalus was identified in 12 (21%) on pMRI and 13 (23%) on CN. Interrater agreement on pMRI was almost perfect for bifrontal diameter (ICC, 0.94; 95% CI, 0.89-0.97) and Evans index (ICC, 0.92; 95% CI, 0.86-0.95) and substantial for determination of hydrocephalus (κ = 0.72), all
conclusionsLow-field pMRI demonstrated excellent interrater agreement and strong concordance with CN in assessing ventricular size, highlighting its potential as an effective point-of-care tool for neurocritical care applications.
