Fetal Cardiac Function in Early Labour and Intrapartum Outcomes: A Prospective Observational Study.
Observational study in BJOG : an international journal of obstetrics and gynaecology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveTo assess fetal myocardial deformation in normo-oxygenated foetuses in early labour and its relationship with intrapartum outcomes.
designSingle centre prospective study.
settingReferral tertiary maternity unit. POPULATION: Uncomplicated singleton term pregnancies in early labour.
methodsTwo-dimensional (2D) ultrasound clips of the 4-chamber view of the fetal heart were collected in labour and sent to TomTec software for the offline speckle tracking echocardiography analysis. The left (LV) and right ventricular (RV) myocardial (MyoGLS) and endocardial longitudinal (EndoGLS) strain were evaluated.
main outcome measuresOperative delivery including caesarean or assisted vaginal birth due to suspected intrapartum fetal compromise (IFC) as defined by standard CTG criteria.
resultsIn total, 208 cases were included. Operative delivery due to suspected IFC was recorded in 20 (9.6%) cases and was associated with higher LV ejection fraction (EF) (47.4 + 8.2 vs. 40.9 + 12.9%, p = 0.03) and increased RV MyoGLS (-15.9 + 4.0 vs. -12.5 + 4.3%, p < 0.01) and RV EndoGLS (-17.7 + 4.4 vs. -14.3 + 4.7%, p < 0.01) compared to cases not having operative delivery due to suspected IFC. Maternal age (OR 1.138, 95% CI [1.010-1.281], p = 0.03), baseline fetal heart rate at acquisition (OR 1.068, 95% CI [1.007-1.134], p = 0.03) and RV MyoGLS (OR 0.575, 95% CI [0.366-0.903], p = 0.02) were independently associated with the primary outcome.
conclusionsIncreased right ventricular myocardial deformation is associated with operative delivery due to suspected IFC, suggesting an early cardiac response to labour-related hypoxia.
