Epidemiological analysis and risk factors of recurrent pulmonary tuberculosis in Western Zhejiang Province, China (2007-2024).
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
Background: Recurrent pulmonary tuberculosis (PTB) after successful treatment is a significant challenge for current TB control efforts. This study investigated the epidemiological characteristics of recurrent PTB in western Zhejiang Province, aiming to identify risk factors for recurrence and predictors of retreatment outcomes, thereby providing a scientific basis for targeted prevention and management. Methods: This retrospective cohort study utilized surveillance data from the Tuberculosis Information Management System in Quzhou, Zhejiang, from January 1, 2007, to December 31, 2024. Recurrence-free intervals were analyzed to identify temporal patterns, and multivariable Cox proportional hazards regression models were employed to determine independent risk factors for recurrence and adverse retreatment outcomes. Results: Among 28,458 patients, 897 (3.15%) experienced recurrence. These cases were predominantly male (79.2%), older (mean age, 61.6 years), and farmers (80.3%). Recurrence-free intervals significantly shortened with subsequent episodes, dropping from a median of 804 days (95% CI, 740-900) for the first recurrence to 495 days (95% CI, 394-737) for the second ( Conclusion: Nearly half of the recurrences occurred within 2 years after treatment completion, and recurrence-free intervals progressively shortened with repeated episodes. The older population (≥65 years) faced a dual burden, identified as the primary risk group for both recurrence and adverse retreatment outcomes. For the risk factors of recurrence and the success of treatment, it is necessary to further refine and explore the influencing factors.
