Significant Increase in Excess Deaths after Repeated COVID-19 Vaccination in Japan.
Article in JMA journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Although Japan recorded the world's highest rate of COVID-19 messenger ribonucleic acid (mRNA) vaccination doses per capita, COVID-19 cases and deaths exploded after the emergence of the Omicron variant, followed by a significant increase in excess deaths in 2022 and 2023. Although several hypotheses have been proposed to explain these phenomena, the truth remains to be established because sufficient studies and data disclosures have not been conducted to adequately investigate the possible contribution of mRNA vaccines. The causes of the excess deaths from not only COVID-19 but also other factors after repeated mRNA vaccinations must be elucidated, given this could provide valuable information to help combat future infectious disease outbreaks.
