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

backgroundPatients with severe coronavirus disease 2019 (COVID-19) have been reported to show hypoxia without displaying typical clinical signs or symptoms, called "happy hypoxia." To explore the potential of happy hypoxia as a distinctive symptom of COVID-19, we compared vital signs in the triage phase between patients with and without COVID-19.

methodsWe retrospectively identified emergency patients with and without COVID-19 admitted to Rakuwakai Marutamachi Hospital, Kyoto, Japan, between January 2021 and December 2021. RESULTS AND

conclusions317 patients were analyzed. Multivariate logistic regression analysis, including all vital signs, demonstrated that the respiratory rate was not statistically associated with COVID-19 (odds ratio, 0.94, p = 0.058), suggesting that happy hypoxia may not be a distinct hallmark of COVID-19.
