Table 1 Demographic and clinical characteristics of the study population (N = 1,947) stratified by BMI groups. The table includes data on asthma, chronic obstructive pulmonary disease (COPD), other lung diseases, and non-lung disease cases. Presented variables include age, gender, smoking status, and IOS parameters
