Drug resistance patterns among tuberculosis patients at a tuberculosis designated hospital in Yunnan: a retrospective analysis of the 2013-2022 period.

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
backgroundDrug-resistant tuberculosis (TB) pose a significant impact on public health challenge in China. This study aimed to characterize the drug resistance patterns among TB patients at a designated tuberculosis hospital of Yunnan province over the past decade and identify risk factors associated with the severity of drug resistance.
methodsClinical data were retrospectively collected from The Third People's Hospital of Kunming City (a designated TB hospital in Yunnan) between 2013 and 2022. Inclusion criteria required patients with confirmed pulmonary TB who underwent phenotypic drug susceptibility test (DST) and had positive sputum culture results. Temporal trends of levels of resistance are visualized and statistically predicted by demographic characteristics using ordinal odds ratios from ordered logistic regression.
resultsAmong 76,455 TB patients diagnosed during the study period, 4,303 had phenotypic DST results available. Most patients were aged 14-30 years. The incidence of most drug resistance types gradually declined after 2017, reaching the lowest levels in 2021, but increased thereafter. Male sex and middle age (30-60 years) being were significant risk factors for severe levels of drug-resistant tuberculosis.
conclusionsDrug-resistant tuberculosis remains a public threat in the study area, especially in the above sub-populations. There is a need to conduct more studies to reveal the mechanisms of DR-TB transmission in these high-risk groups.
