Discomfort of noninvasive ventilation, high flow nasal cannula oxygen, and conventional oxygen implemented after extubation in non-COPD patients.

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
backgroundDiscomfort of noninvasive respiratory supports remain controversial. In the present study, the discomfort of high flow nasal cannula oxygen, noninvasive ventilation, and conventional oxygen therapy were evaluated in the post-extubation period.
methodsNoninvasive ventilation alternating with high flow nasal cannula oxygen or conventional oxygen therapy were implemented for 48 h following extubation in patients free of chronic obstructive pulmonary disease. Using a 10-cm visual analog scale, the discomfort of the interface (oxygen mask, nasal prongs or facial mask), was self-evaluated by 264 patients after extubation whereas the discomfort of the respiratory support (conventional oxygen therapy or high flow nasal cannula oxygen alternating with noninvasive ventilation) was evaluated by the nurses in 306 patients. Evaluations were performed in patients at high (n = 127) and low (n = 179) risk of postextubation respiratory failure, 6, 24 and 48 h after extubation.
resultsFacial mask was the source of a significant and persisting self-evaluated discomfort. Nasal prongs and oxygen mask were less uncomfortable, with a progressive reduction of the discomfort with time. High flow nasal cannula oxygen alternating with noninvasive ventilation caused a significant and persisting nurse-reported discomfort. Conventional oxygen therapy was significantly less uncomfortable, and the degree of discomfort was not different in patients at high and low risk of extubation failure.
conclusionsNoninvasive ventilation was associated with a significant and persisting discomfort whereas high flow nasal cannula oxygen-induced discomfort remained limited. After 48 h, discomfort resulting from high flow nasal cannula oxygen and conventional oxygen therapy was similar and negligible.
