1 · What the graph read from it

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.

2 · The registry

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

Persistent left superior vena cava is a malformation of cardinal veins. We report a case of a secundigravida who had many fetal ultrasound examinations - first performed by an obstetrician (who described fetal mediastinum as "abnormal"), second by other obstetrician, who performed basic fetal echocardiographic examination and diagnosed persistent left superior vena cava. The woman was referred to a tertiary center for detailed fetal echocardiography. The diagnosis of persistent left superior vena cava with agenesis of the right superior vena cava was confirmed. The anomaly had no influence on fetal hemodynamic stability, fetal life, delivery and early postnatal period. After delivery, the neonate was under observation for further anomalies, aortic coarctation in particular. Prenatal and postnatal management was summarized. Literature review is presented.
