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

Central vein catheterization is a common procedure performed on patients under intensive care. The safe and successful placement of the central venous catheter depends on vein size. Although used for this purpose, the Trendelenburg position can be hazardous in some patients. The aim of this study was to compare the effects of the Trendelenburg and passive leg raising (PLR) positions on the size of the right internal jugular vein (IJV) in mechanically ventilated patients under intensive care. Seventy-eight mechanically ventilated patients under intensive care were included into the study. Sonographic images of the right IJV were recorded in supine (control), 10° Trendelenburg and 40° PLR positions. Anterior-posterior and transverse diameter, cross-sectional area (CSA), and depth were calculated from the recorded images. The size of the right IJV (CSA, transverse and vertical diameters) was significantly larger in the Trendelenburg and PLR positions than in supine position. An increase of 26% in the IJV CSA was obtained in the Trendelenburg position and 23% in the PLR position, compared to the supine position. There was no significant difference between the measurements obtained from the Trendelenburg and PLR positions. The study shows that the Trendelenburg and PLR positions increase the size of the IJV to a similar extent in mechanically ventilated patients under intensive care.
