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

objectiveTo verify whether a large-scale international volleyball competition could be conducted safely using the bubble method, both for our participating team and as a whole.

methodsAll 32 men's and women's teams were gathered in one place and a large-scale international volleyball competition was held for over a month without spectators using the bubble method. More than 1,000 people participated in the event, and 572 volleyball players played a total of 248 matches during the competition. There were 54 participants from Japan, including 27 male and female staff and players each. There was one team doctor for both men and women. A total of 2,250 PCR tests and 7,920 antigen tests were performed over 38 days. We investigated the incidence of infection in our team and in all participating teams.

resultsThere were 9 fever cases from our men's team, but all of them tested negative for COVID-19. Overall, a total of 10,170 tests were performed and only one was positive.

conclusionIn order to ensure the health and well-being of all participants, the indoor competition was concluded safely without the occurrence of COIVD-19 clusters in the bubble system with strict adherence to various strict protocols of COVID-19.
