Comparison Between Respiratory-Triggered and Free-Breathing Signal Acquisition Methods for Single-Voxel Phosphorus Magnetic Resonance Spectroscopy of the Liver on a Clinical System.
Article in Journal of magnetic resonance imaging : JMRI, 2026. 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
backgroundThe optimal protocol for clinical liver PURPOSE: To compare STUDY TYPE: Prospective. POPULATION: 24 volunteers (19 male/5 female). FIELD STRENGTH/SEQUENCE: 3 T MRI; single-voxel
methodsSTATISTICAL TEST: Paired t-tests and Bland-Altman analysis were used. A p value < 0.05 was considered significant.
resultsScan duration was significantly longer for RT (15 min 44 s) than FB (12 min 56 s). No significant differences were observed for SNR (p = 0.570), NADPH/(PME + PDE) (p = 0.931), PME/γ-ATP (p = 0.556), Pi/γ-ATP (p = 0.931), α-ATP/γ-ATP (p = 0.332), or NADPH/γ-ATP (p = 0.394). Significant differences were noted for PDE/γ-ATP (RT 1.68 vs. FB 1.35, p = 0.003) and PME/PDE (RT 0.434 vs. FB 0.489, p = 0.046). Bland-Altman analysis showed near-zero fixed biases and no proportional bias, with limits of agreement from -0.53 to 0.62 (PME), -0.30 to 0.30 (Pi), -0.41 to 1.07 (PDE), -0.45 to 0.43 (α-ATP), and -0.80 to 0.90 (NADPH).
