Sex differences in clinical and radiographic features of nontuberculous mycobacterial pulmonary disease in a Chinese population

Puntos clave

This research aims to explore the differences in clinical and radiographic features of NTM-PD between sexes in a Chinese population.
Retrospective analysis of 218 patients with NTM-PD in China, stratified by sex.
Comparison of clinical characteristics, comorbidities, laboratory parameters, and CT findings.
Utilization of logistic regression to analyze associations between sex and radiographic manifestations.
Significant differences found in clinical and radiographic features between male and female patients with NTM-PD.
Specific statistical outcomes were reported, though detailed statistics were not provided in the abstract.
Limitations noted include single-center design and lack of long-term follow-up data.

Resumen

BACKGROUND: Sex-related differences in nontuberculous mycobacterial pulmonary disease (NTM-PD) may influence both clinical presentation and radiographic phenotypes; however, evidence from Chinese populations remains limited. RESEARCH DESIGN AND METHODS: This retrospective study included 218 patients with NTM-PD in China. Patients were stratified by sex. Clinical characteristics, comorbidities, laboratory parameters, and high-resolution computed tomography findings were compared. Logistic regression analyses were performed to evaluate the association between sex and specific radiographic manifestations. RESULTS: = 0.118). CONCLUSIONS: Significant sex differences exist in the clinical and radiographic phenotypes of Chinese patients with NTM-PD. Limitations include the single-center retrospective design, relatively small sample size, lack of long-term follow-up data, and absence of sex hormone and environmental exposure assessments.
