Crowded Spaces, Contagious Risks: Comparing COVID-19 Incidence After Outdoor Concerts Among University Members and the Community, Republic of Korea, 2022.
Article in Journal of Korean medical science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled 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.
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
backgroundA university festival, including outdoor concerts, was held from May 2 to 4, 2022, following the relaxation of coronavirus disease 2019 (COVID-19) restrictions in Korea. This study aimed to assess its impact on COVID-19 cases among university members.
methodsWe collected daily COVID-19 case data from university and local government websites and conducted a causal impact analysis using a Bayesian structural time series model.
resultsThe analysis revealed a significant increase in cases following the event. From May 6 to 29, 2022, the university recorded an average of 5.8 daily cases (total: 138 cases). In the counterfactual scenario without the event, the estimated number of daily cases was 2.5 to 3.0 (total: 57.1 to 72.0 cases) based on three prediction models. The outdoor concerts were associated with an approximately twofold increase in COVID-19 cases among university members.
conclusionDespite a declining trend in community cases, these findings underscore the potential risks of crowded outdoor gatherings in spreading COVID-19 and highlight the need for caution at such events.
