Prenatal ultrasound diagnosis and prognosis of persistent left superior vena cava: a 10-year retrospective cohort study at a single center in China.

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
Objective: To describe the prenatal ultrasound characteristics of persistent left superior vena cava (PLSVC) in fetuses and its correlation with related malformations, chromosomal abnormalities, and clinical outcomes. Methods: A 10-year retrospective analysis of the clinical and ultrasound data of 898 fetuses diagnosed with PLSVC at our center was conducted. Ultrasound characteristics of PLSVC type were summarised systematically, and incidence rates of abnormalities and pregnancy outcomes of PLSVC types were determined. Results: Diagnosing PLSVC requires the 4CV, 3VV and 3VT views, while auxiliary classification requires parasagittal and innominate vein views. PLSVC ultrasound features include coronary sinus dilation and an additional vascular cross-section on the left side of the pulmonary artery. Types I and II PLSVC involved 94.2% vs. 5.8% of cases, respectively. Type I PLSVC had lower incidence of abnormalities (70.3%) than Type II (100%; Conclusion: Multifaceted prenatal ultrasound is valuable for classifying and categorizing fetal PLSVC. Classifying PLSVC and assessing accompanying abnormalities is key to determining prognosis. Type II or non-isolated PLSVC, when accompanied by intracardiac and extracardiac abnormalities, requires enhanced genetic testing and multidisciplinary management. Contrariwise, Type I or isolated PLSVC has good prognosis.
