Quantitative MRI Values for Atrial and Ventricular Parameters in Altitude-Dwelling Youth.
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. Cited by 2 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
backgroundThe hypoxic environment on the Qinghai Plateau significantly exacerbates myocardial remodeling, with sex/ethnicity-specific variations in cardiac parameters among local youth. Current cardiac MRI reference values lack data from physiologically adapted populations on this plateau. PURPOSE: To establish sex- and ethnicity-specific normative reference values for cardiac structure and function in native Qinghai Plateau young adults and to analyze their correlations. STUDY TYPE: Prospective. SUBJECTS: 101 healthy young volunteers (15-24 years) residing on the Qinghai Plateau, including 44 males and 57 females; 37 Han people (20 males and 17 females), 20 Tibetan people (3 males and 17 females); the remaining 44 people are from the Hui, Tu, Salar, and Mongolian ethnic groups. FIELD STRENGTH/SEQUENCE: Steady state free precession cine sequence at 3.0 T. ASSESSMENT: Circle CVI42 software was used to quantify cardiac chamber structural and functional parameters from cine images. All parameters were normalized to body surface area (BSA). STATISTICAL TESTS: Sex- and ethnicity-specific reference ranges were defined as mean ± 1.96 SD. Sex/ethnicity group comparisons were assessed with independent samples t-tests. Correlations between parameters were visualized through correlation heatmaps. A p value < 0.05 was considered significant.
resultsCompared to females, males exhibited significantly larger cardiac parameters, including left atrial (LA) and right atrial (RA) diameters (p < 0.05). In the four-chamber view, the left atrial area was larger in males (end-systolic 1688.57 ± 326.75 vs. 1562.68 ± 238.01 mm
conclusionThe results showed that plateau environment, gender differences, and ethnic differences are all influencing factors of atrioventricular parameters and emphasized the strong correlation between physical parameters and cardiac structure. STAGES OF TECHNICAL EFFICACY: Stage 1. EVIDENCE LEVEL: Evidence Level 1.
