Epidemiology of surgical occupational exposures in an infectious disease hospital: a 5-year retrospective study.
Article in Frontiers in public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 the epidemiological characteristics and associated factors at the univariate level of surgical occupational exposures in an infectious disease hospital over the past 5 years, and to provide evidence for developing targeted prevention strategies. Methods: We retrospectively collected surgical occupational exposure reports from an infectious disease hospital between January 2020 and December 2024, including 104 valid cases. Statistical analysis was performed using R 4.4.2 software to describe the temporal, demographic, departmental, role-based, and exposure-type distributions, along with a univariate analysis. Results: The incidence of occupational exposure showed an increasing trend year by year, with a significant rise in 2024. Males accounted for 71.2% of the exposures, with the majority aged 25-39 years. Surgical assistants had the highest exposure proportion (50.0%), and the departments with the most exposure were Infectious Surgery and Orthopedics (18.3% each). The primary type of exposure was sharp injuries (60.6%). Significant differences were observed among the different surgical roles in terms of sex, age, education, and department ( Conclusion: This study revealed a heterogeneous risk pattern for surgical occupational exposure in an infectious disease hospital. Surgical assistants and the Orthopedics/Infectious Disease Surgery departments constituted the core high-risk cluster, confirming that job role and departmental specialty are more critical determinants of exposure risk than individual experience. Notably, the recurrence of nearly half of all exposure events provides compelling evidence that current prevention strategies-centered predominantly on training and personal protective equipment-exhibit structural failure in effectively breaking the chain of exposure. Therefore, effective risk control must transcend individual behavioral discipline and shift toward a precision prevention system anchored in engineering controls and systemic workflow interventions.
