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
Introduction: Tuberculosis (TB) represents one of China's most significant infectious disease, with inter-provincial population migration posing a challenge to controlling its spread. This study examined TB cases among inter-provincial migrants across China from 2019 to 2023. Methods: TB surveillance data were extracted from China's Tuberculosis Information Management System and analyzed using R software (version 4.4.0). After information desensitization, the relevant information of TB patients with differing current and permanent address codes was extracted. Results: Between 2019 and 2023, we identified 123,945 TB cases among inter-provincial migrants, representing 4.03% (123,945/3,077,951) of all reported TB cases. The primary destination provincial-level administrative divisions (PLADs) for TB patients were Guangdong (48,183 cases, 38.9%), Zhejiang (27,383 cases, 22.1%), Fujian (8,582 cases, 6.9%), Beijing (7,959 cases, 6.4%), and Shanghai (7,403 cases, 5.9%), collectively accounting for 80.3% of all inter-provincial migrant TB cases. The PLADs with the highest outflow of TB migrants were Sichuan (15,155 cases, 12.23%), Hunan (14,707 cases, 11.87%), Guizhou (13,927 cases, 11.24%), Jiangxi (8,892 cases, 7.17%), and Hubei (8,441 cases, 6.81%). Among these migrant cases, 66.2% were male, 93.0% were newly diagnosed, 2.4% exhibited drug resistance. The proportion of individuals aged 45-64, aged ≥65 and re-treated exhibited a significant annual increase ( Conclusion: From 2019 to 2023, the characteristics of TB among inter-PLADs migrant patients have undergone certain changes. The migration of TB primarily flows from economically weaker regions to more developed areas, with the main destination PLADs relatively stable. Effective TB control among inter-PLADs migrants requires targeted screening programs focusing on individuals from major source and destination PLADs. Tailored strategies should be developed based on the migration patterns of different PLADs.
