The position of the inferior vena cava-right atrium junction on simple radiography: implication for optimal veno-venous extracorporeal membrane oxygenation cannula tip position.

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
backgroundExtracorporeal membrane oxygenation (ECMO) is increasingly used. For effective oxygenation, position of cannula tip is important. The objective of this study is to identify the position of the inferior vena cava-right atrium junction (IRJ) using the vertebral body unit (VBU) and carina. This may be useful if applied to the assessment of ECMO cannula tip positions.
methodA total of 182 patients who underwent chest computed tomography (CT) and supine chest radiography (CXR) between January 2017 and July 2018 were included, who had not previously received ECMO support. The position of the IRJ was evaluated using VBU and the efficacy of the VBU for locating the IRJ with the carina was analyzed.
resultThe mean distance (SD) from carina to IRJ was 79.2 (9.6) mm on chest CT. The mean distance in VBUs (SD) at the level of the carina was 22.3 (1.5) mm on chest CT and 23.3 (2.1) mm on CXR. The mean IRJ position was 3.6 VBUs below the carina on CT and 3.4 VBUs below on CXR with 95% limits of agreement between -0.05 and 0.5.
conclusionsThe mean position of the IRJ was estimated to be 3.4 VBUs below the carina on supine CXR. This may be useful if applied to the assessment of ECMO cannula tip positions.
