Effect of Body Position on Dynamic Apparent Diffusion Coefficient Changes During the Cardiac Cycle in the Human Brain.
Article in Journal of magnetic resonance imaging : JMRI, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundDynamic changes in the apparent diffusion coefficient (ΔADC) during the cardiac cycle reflect water molecule fluctuations in the brain and intracranial conditions. While body position strongly affects intracranial conditions, the relationship between ΔADC and body position has been less explored, as conventional MRI is typically performed only in the supine position. PURPOSE: To investigate ΔADC and mean ADC (ADC STUDY TYPE: Prospective. SUBJECTS: Nine healthy volunteers (all males; mean age, 23.5 years). FIELD STRENGTH/SEQUENCE: 0.4 T, electrocardiographically synchronized single-shot diffusion echo-planar imaging sequence with b-values of 0 and 500 s/mm ASSESSMENT: ADC maps were generated at multiple cardiac phases in each subject in the sitting and supine positions. For each position, an ADC STATISTICAL TESTS: Wilcoxon signed-rank test. Significance was set at p < 0.05.
