Difference in clinical courses and causes of COVID-19-related deaths in hospitalized patients infected with omicron and delta variants: A retrospective study in Japan.
Article in GHM open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Despite the lower rate of severe illness associated with the omicron variant than the delta variant, more deaths have occurred among patients with mild-to-moderate COVID-19 in Japan since the omicron variant surge during the sixth wave. This study aimed to elucidate the background, clinical course, and causes of death in patients with COVID-19. We conducted a retrospective observational study on patients with COVID-19 admitted to the National Center for Global Health and Medicine who subsequently died during the delta (July-September 2021) and omicron variant outbreaks (December 2021-August 2022). Among the 20 patients who died during the delta variant epidemic, the main causes of death were pneumonia (
