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

Background: Compared with conventional pressure support ventilation (PSV), noisy PSV offers a certain degree of pressure variability, which might benefit the process of weaning from mechanical ventilation. We investigated respiratory mechanics under different levels of variation during the weaning phase in patients receiving noisy PSV to identify the optimal level of variation. Methods: This self-controlled before-and-after study of mechanically ventilated patients in the weaning phase was conducted from September 2020 to October 2022. Each eligible patients received noisy PSV with 0%, 15%, 25%, or 35% variation in a random order. Their respiratory mechanics were collected 1 h after the pressure variation level was switched and compared. Results: The study found that noisy PSV significantly improved patients' respiratory system compliance at variation levels of 25% and 35% (0% Conclusions: Pressure variation at level of 25% or 35% could improve patients' respiratory system compliance and shorten the inspiratory trigger delay time, potentially being optimal in noisy PSV during the weaning phase from mechanical ventilation.
