The 24-Segment Global Sphericity Index Is Useful for Assessing Fetal Cardiac Function and as an Indicator of Fetal Well-Being.
Article in Cureus, 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
backgroundAutomated technologies have become increasingly vital in fetal cardiac assessment. Fetal heart quantification (HQ), which utilizes two-dimensional speckle tracking, provides quantitative measures of morphology and function. This study aims to identify the progression of many fetal cardiac function parameters during pregnancy in normal pregnant women and to determine which parameters are relevant to fetal well-being and worth considering.
methodsWe conducted a prospective observational study involving fetuses of 26 normal pregnant women to evaluate 27 fetal HQ parameters (including strain, sphericity indices, and four-chamber view measurements) across gestation. Factor analysis was used to identify indicators of fetal and neonatal well-being. Additionally, we analyzed a case of fetal growth restriction (FGR) complicated by a double-outlet right ventricle (DORV) and total anomalous pulmonary venous connection (TAPVC).
resultsFour parameters, which were tricuspid valve width, tricuspid valve length, the area of the four-chamber view, and right ventricular end-diastolic area (RVEDA), might be particularly informative. It is possible to perform serial assessments of fetal cardiac contractile development throughout gestation. In cases of FGR with DORV and TAPVC, fetal HQ detected abnormal right ventricular loading and impaired contractility. In cases of FGR with DORV and TAPVC, fetal HQ detected abnormal right ventricular loading and impaired contractility.
conclusionFetal HQ provides a reproducible, quantitative approach to fetal cardiac assessment. These key indices may serve as potential indicators of fetal well-being and facilitate the early detection of cardiac dysfunction in high-risk pregnancies.
