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 current status and influencing factors of latent tuberculosis infection among new students in Taishan District in 2025, providing data support for the formulation of tuberculosis prevention and control strategies in schools. Methods: A total of 38,863 new students in 2025 were selected as the study subjects and underwent standardized PPD skin tests. Statistical analysis was performed using SPSS software, with group comparisons conducted via chi-square tests, and a multivariate logistic regression model employed to analyze influencing factors. Results: In 2025, 38,863 new students in Taishan District underwent valid screening, with an overall screening rate of 92.70%. PPD test results showed that 30,438 students (78.32%) were negative, 2,243 (5.77%) were strongly positive, and the total number of latent tuberculosis infection cases was 5,395, with a latent infection rate of 13.88%. Multivariate analysis revealed that male gender (OR = 0.880, 95%CI: 0.829-0.935), junior high school (OR = 0.331, 95%CI: 0.230-0.477), senior high school (OR = 0.471, 95%CI: 0.404-0.550),vocational school (OR = 0.531, 95%CI: 0.457-0.618); junior college (OR = 0.690, 95%CI: 0.644-0.739); new students aged 17-18 years (OR = 0.787, 95%CI: 0.737-0.841), and students with no history of tuberculosis exposure (OR = 0.096, 95%CI: 0.079-0.116) had a relatively lower risk of latent infection. Conclusion: The prevalence of latent tuberculosis infection and the rate of strongly positive results among new students in Taishan District in 2025 were relatively high. Female students, undergraduate students, those aged 19 years and older, and students with a history of tuberculosis exposure were identified as high-risk groups for latent infection. Screening of incoming new students should be strengthened, and individuals with latent infection should undergo dynamic monitoring and preventive interventions to reduce the risk of tuberculosis occurrence on campus.
