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: Fetal cardiac tumors are relatively rare among congenital heart diseases (CHDs). The presence of cardiac rhabdomyoma (CR) during fetal development may serve as the earliest clinical sign of tuberous sclerosis complex (TSC), with multiple CRs being a strong predictor of TSC. This study aimed to summarize the ultrasound image characteristics of fetal CR and follow up the comprehensive information of prenatal magnetic resonance imaging (MRI) examination, genetics, and postnatal changes in clinical outcomes to improve the detection rate and optimize the outcome of the diagnosis and treatment. Methods: A retrospective analysis was performed on prenatal ultrasound diagnostic data from 36 fetal CRs, including lesion characteristics (number, location, size, and associated complications), as well as follow-up information during pregnancy and within 1 year of birth. Results: Among the 36 cases of CR, 11 patients (31%) underwent MRI examinations. Of these, five cases presented with subependymal nodules on cranial MRI, suggestive of TSC; one case showed asymmetric bilateral lateral ventricles and dilation of the vein of Galen; and one case revealed multiple hemorrhages in the cerebral parenchyma and subependymal regions, along with left lateral ventricular enlargement. The remaining four MRI results were negative. Genetic testing identified abnormalities in 6 cases (17%), including five with TSC-related gene mutations and one with a whole exome sequencing (WES) anomaly. Pregnancy was terminated in 12 cases (33%). Postnatal follow-up demonstrated no significant change in CR size in one case, a reduction in CR size in one case, and complete regression of CR in three cases. Conclusions: Echocardiography plays a critical role in diagnosing CR. For fetuses prenatally diagnosed with CR, routine cranial MRI and whole exome genetic testing should be performed to confirm the presence of TSC or other pathogenic variants, which is essential for early clinical intervention and decision-making.
