Cerebral Ventricular Dimensions in Patients with Heart Failure with Reduced Ejection Fraction (HFrEF): A Cross-Sectional MRI Study.
Article in International journal of general medicine, 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
Background: The aim of this cross-sectional case-control study was to measure the cerebral ventricular diameters of patients with heart failure with reduced ejection fraction (HFrEF) using magnetic resonance imaging (MRI) and to investigate their differences compared to healthy controls, as well as their relationship with left ventricular ejection fraction (LVEF). Methods: A total of 104 healthy volunteers and 104 patients with HFrEF (New York Heart Association [NYHA] class II-IV) were included in the study (mean age: 57.2 ± 8.4 vs. 59.7 ± 10.8 years, respectively; p = 0.007). In both groups, LVEF was measured using echocardiography, and cerebral ventricular diameters-including the bifrontal diameter (BFD), bihemispheric diameter (BHD), and frontal horn ratio (FHR)-were measured using MRI. Finally, the Evans index and the anteroposterior diameter of the lateral ventricle index (ALVI) were calculated. Results: The BFD, FHR, ALVI, and Evans index were significantly higher in the HFrEF group than in the healthy control group (BFD: 37.30 ± 3.4 vs. 31.97 ± 2.2, p < 0.001; FHR: 0.32 ± 0.03 vs. 0.28 ± 0.01, p < 0.001; ALVI: 0.44 ± 0.04 vs. 0.38 ± 0.03, p < 0.001; Evans index: 0.27 ± 0.02 vs. 0.23 ± 0.01, p < 0.001). ROC curve analysis demonstrated high diagnostic and discriminatory performance for both indices in distinguishing HFrEF patients from healthy controls (AUC = 0.901 [95% CI: 0.859-0.943], p < 0.001 for ALVI and AUC = 0.903 [95% CI: 0.862-0.944], p < 0.001 for Evans index). Correlation analysis revealed that LVEF was significantly and negatively correlated with both the Evans index (r = -0.550, p < 0.001) and ALVI (r = -0.585, p < 0.001). Conclusion: Cranial ventricular dimensions are significantly increased in patients with HFrEF compared to healthy controls, and these indices are inversely correlated with LVEF systolic impairment.
