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

In clinical studies, the partial pressure of oxygen (PaO2) and oxygen pulse saturation are the main variables used to assess blood oxygenation and define the threshold of hypoxia/hyperoxia and hypoxemia/hyperoxemia. Determination of the optimal oxygenation target has generated a lot of interest in recent years, mainly because of the potential risk of worse outcomes associated with hyperoxia, whereas the risk associated with hypoxia has been already well known. In this short narrative review, we recall some fundamental elements of physiology regarding the meaning of PaO2, the diffusion of oxygen to cells, the definitions of hyperoxemia and hyperoxia and the mechanisms of oxygen toxicity to provide a better understanding of these concepts, to which intensive care clinicians are frequently confronted. PaO2 provides only limited information about oxygen concentration carried by blood and does not allow to determine whether cells are exposed to hyperoxia. This should be considered for the design of future studies that aim to determine optimal oxygenation target and by clinicians for their daily practice.
