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

Venovenous extracorporeal membrane oxygenation (VV ECMO) relies on effective blood drainage, and cannula design plays a crucial role in optimizing blood oxygenation. Recirculation, where oxygenated blood returns to the drainage cannula without systemic circulation, can negatively impact ECMO efficacy. It was hypothesized that drainage cannulae with a longer side hole portion would reduce recirculation and improve blood oxygenation. This in vitro study investigated the impact of the length of the side hole portion and the intervals of the side holes on blood oxygenation in a simulated VV ECMO circuit. Five cannulae were prepared with the following side holes: (a) 1-cm intervals from the tip to 5 cm; (b) 1-cm intervals from the tip to 10 cm; (c) 1-cm intervals from the tip to 15 cm; (d) 3-cm intervals from the tip to 15 cm; and e) 5-cm intervals from the tip to 15 cm. With blood drained from the right atrium and returned to the superior vena cava, recirculation rates and PaO
