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

backgroundUmbilical vein catheterization is relatively straightforward procedure because the vein is easily recognized as a single, large, thin-walled vessel. However, anomalies of the umbilical vessels, such as the multivessel cord, which embeds more than two arteries or more than one vein, can result in catheter misplacement. CASE PRESENTATION: We present a unique case of a supernumerary patent umbilical artery in an asphyxiated term neonate, which resulted in the misplacement of the umbilical venous catheter in one of the three arteries. The diagnosis of artery cannulation was made through a comprehensive analysis of the patient's blood gases, the use of a pressure transducer to confirm the presence of a pulsatile arterial signal, and the interpretation of a chest X-ray. Subsequently, the catheter was removed without complication. A more detailed examination of the umbilical cord revealed the presence of three arteries and a vein, which was then successfully cannulated.

conclusionsThis case reinforces the notion that the umbilical cord may include more than three vessels, and that umbilical vein cannulation requires prior meticulous observation of the number of vessels to prevent misplacement of the catheter.
