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: Electrocardiogram (ECG) triggering in cardiac magnetic resonance (MR) faces limitations with high-field systems (≥3.0T) due to magnetohydrodynamic (MHD) artifacts. This study aimed to evaluate the feasibility of using finger-pulse triggering for cardiac MR T1 mapping by comparing image quality and native T1 quantification with conventional ECG triggering. Methods: Patients who underwent cardiac MR examination between March and April 2024 were prospectively and consecutively enrolled in the study. All the patients underwent identical pre-contrast T1 mapping with both ECG- and pulse-triggering acquisitions using a modified Look-Locker inversion-recovery (MOLLI) 5(3)3 sequence, covering short-axis views at basal, mid, and apical slices of the left ventricle. Three radiologists independently evaluated image quality using the Likert scale (range, 1-5). Two radiologists manually delineated myocardial regions of interest (ROIs) on native T1 maps to quantify segmental native T1 values. Paired Results: A total of 15 participants were included in the study (mean age: 41±19 years; 60% male). ECG and finger-pulse triggering demonstrated equivalent diagnostic image quality (median scores: 4.0 Conclusions: Finger-pulse triggering demonstrates comparable accuracy and reliability to ECG triggering in cardiac MR T1 mapping, offering a viable clinical alternative for patients with ECG distortion or triggering failure.
