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

backgroundReintubation is not an uncommon occurrence following extubation and discontinuation of mechanical ventilation. In COVID-19 patients, the proportion of reintubation may be higher than that of non-COVID-19 patients. Furthermore, COVID-19 patients may have a higher risk for developing laryngotracheal stenosis, along with a higher proportion of reintubation than in non-COVID-19 patients. Our understanding of the proportion of reintubation in COVID-19 patients is limited in Japan. Additionally, the reasons for reintubation have not been adequately examined in previous studies outside of Japan. Thus, the present study aimed to describe the proportion and causes of reintubation among COVID-19 patients in Japan.

methodsThis was a multicenter observational study that included 64 participating centers across Japan. This study included mechanically ventilated COVID-19 patients who were discharged between April 1, 2020 and September 30, 2020. The outcomes examined were the proportion and causes of reintubation.

resultsA total of 373 patients were eligible for inclusion in the current analysis. The median age of patients was 64 years and 80.4% were male. Reintubation was required for 35 patients (9.4%) and the most common causes for reintubation were respiratory failure (71.4%; n = 25) and laryngotracheal stenosis (8.6%; n = 3).

conclusionsThe proportion of reintubation among COVID-19 patients in Japan was relatively low. Respiratory failure was the most common cause for reintubation. Reintubation due to laryngotracheal stenosis accounted for only a small fraction of all reintubated COVID-19 patients in Japan.
