Distribution and epidemiological characteristics of nontuberculous mycobacterium species in jianghan plain.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Pulmonary nontuberculous mycobacteria (NTM) disease is an increasing public health concern in China. This study aimed to describe the epidemiology of pulmonary NTM disease in the Jianghan Plain region of Central China. From 2021 to 2023, we collected specimens with positive mycobacterial cultures from the Jianghan Plain and identified species using fluorescence PCR melting curve analysis. We documented demographic characteristics, treatment history, laboratory examination results, and comorbidities of patients with pulmonary NTM disease. From 2021 to 2023, 419 cases of NTM were identified among 5,608 clinical specimens collected from the Jianghan Plain, accounting for 7.47% (419/5,608) of isolates. Among patients with pulmonary NTM, ages ranged from 16 to 90 years, with a median age of 64 years. The majority of cases (56.32%) occurred in patients over 60 years of age. The predominant species identified were Mycobacterium intracellulare (224 cases, 53.46%), Mycobacterium abscessus (91 cases, 21.72%), Mycobacterium avium (27 cases, 6.44%), Mycobacterium gordonae (25 cases, 5.97%), and Mycobacterium kansasii (19 cases, 4.53%). The risk of developing Mycobacterium abscessus disease significantly decreased with advancing age. Compared to patients with Mycobacterium intracellulare disease, those with pulmonary Mycobacterium abscessus disease were significantly more likely to present with hemoptysis. No other significant differences in tuberculosis history or comorbidities were observed between patients with Mycobacterium intracellulare and Mycobacterium abscessus infections. The isolation rate of NTM in the Jianghan Plain from 2021 to 2023 remained stable, slightly exceeding the national average in China. Mycobacterium intracellulare was the most prevalent pathogenic NTM species, followed by Mycobacterium abscessus. Hemoptysis was identified as an independent risk factor for pulmonary disease caused by M. abscessus.
