Risk factors associated with COVID-19 infection among Chinese elite athletes during overseas training and competitions: a large-scale cross-sectional survey.

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
Objective: To analyze COVID-19 infection incidence and risk factors among Chinese national team members during overseas training and competitions (April-October 2022) to inform prevention for international events. Methods: A nationwide cross-sectional survey used electronic questionnaires distributed to 69 national teams. A total of 1,020 valid questionnaires were included for analysis, covering athletes, coaches, medical staff, team leaders, and other support personnel. The χ Results: The overall infection rate was 35.5%. Infection rates differed significantly across occupational groups: athletes had the highest rate (37.9%), followed by coaches (29.8%) and team leaders (21.7%). Personnel who participated in both overseas training and competitions presented a significantly higher infection rate (47.9%) than did those who only participated in competitions (19.0%) ( Conclusion: Infection risk among national team members abroad clustered by role, assignment type, and behaviors. Elevated risk was linked to intensive training schedules, suboptimal implementation of prevention protocols, and frequent contact with foreign personnel. Multifaceted interventions-source control, rigorous process management, and strict adherence to personal protective measures-should be strengthened to reduce infection risk.
