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: Care-seeking delay among students with tuberculosis (TB) poses a significant barrier to school-based TB prevention and control. Such delay facilitates the transmission of Methods: This retrospective study used data from the Chinese National Tuberculosis Information Management System (N-TBIMS). All registered student pulmonary tuberculosis (PTB) cases in Wuhan from January 1, 2012, to December 31, 2025, were included. Multivariable logistic regression was used to identify independent risk factors for delay. Results: A total of 4,920 student PTB patients were enrolled (median age: 19 years, IQR: 17-21,60.54% male). The median time to care-seeking was 9 days (IQR: 3-21), and 37.72% delayed care-seeking for ≥14 days. The delay proportion remained stable at approximately 38.84% during 2012-2019, dropped sharply to 26.55% in 2021, then rebounded to 48.47% in 2022 and reached 55.57% by 2025. Female students experienced a dramatic increase, with rates exceeding 50% during 2022-2025, while male students remained relatively stable. Children aged 3-11 years had the highest delay proportion (55.47%), peaking at nearly 80% in 2023. Multivariable analysis identified key risk factors: non-Han Chinese ethnicity (OR = 2.530, 95% CI: 1.702-3.763, Conclusion: Care-seeking delay (≥14 days) affected 37.72% of student TB patients in Wuhan. The COVID-19 pandemic had a dual impact: strict NPIs in 2020-2021 transiently reduced delays, while post-pandemic health-system strain drove a rebound exceeding pre-pandemic levels. Four distinct risk factors for delay emerged: non-Han students, children aged 3-11 years, passively detected cases via contact tracing or referral, and sputum bacteria-positive patients. Targeted health education, school-based symptom screening, expedited diagnosis after referral or tracing, and multisectoral collaboration among schools, families, and TB control centers are urgently needed to reduce delays and avert school-based outbreaks.
