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

introductionNasal high-flow therapy (HFT) has been shown to improve daytime breathing mechanics in healthy adults as well as the lung function and quality of life in chronic obstructive pulmonary disease (COPD) patients.

methodWe hypothesized that improved breathing mechanics with HFT may further reduce minute ventilation (i.e. decreased work of breathing) during sleep in patients with COPD. In COPD participants we examined the dose effect of HFT (within night randomization of HFT level; 0, 10, 20 and 30L/min) on minute ventilation, oxyhemaglobin saturation and transcutaneous carbon dioxide during wake and sleep. We assessed overnight polysomnography with and without HFT on two separate nights. Paired t-tests were used to compare overnight sleep quality with and without HFT. The association between ventilatory variables and HFT level was assessed using regression analysis.

resultsDuring sleep, HFT decreased minute ventilation by 0.63±0.02L/min per 10L/min nasal airflow by reducing tidal volume (37±6mL per 10L/min; p<0.001) without affecting respiratory rate (p=0.9) or arterial CO

conclusionThe reduction in minute ventilation is greater with higher dead-space volumes (r=0.50; p<0.02) and during wakefulness suggesting that ventilatory responses to HFT are mediated through a reduction in dead-space ventilation. The reduction in ventilation in response to HFT is large enough to reduce respiratory loads. Reducing respiratory loads may avert muscle fatigue, preserve respiratory function, or prevent development of respiratory failure.
