Table 2.
Clinical characteristics of the 110 Korean asthma patients and distribution of pulmonary functions in DSGA and ESGA.
| Asthma patients (n = 110) | DSGA (n = 60) | ESGA (n = 50) | P-value | |
|---|---|---|---|---|
| Age (years) | 49.9 ± 17.1 | 50.0 ± 16.2 | 49.9 ± 18.3 | NSa |
| Sex (male/female) | 49/61 | 31/29 | 18/32 | NSb |
| Pulmonary functions | ||||
| FVC predicted (%) | 87.6 ± 24.2 | 86.2 ± 17.7 | 87.6 ± 20.2 | NSa |
| FEV1 predicted (%) | 77.5 ± 24.2 | 76.0 ± 23.0 | 78.3 ± 26.5 | NSa |
| PEF predicted (%) | 78.3 ± 28.8 | 73.7 ± 25.4 | 79.1 ± 30.6 | NSa |
Values are mean ± SD; DSGA, Deficiency Syndrome Group of Asthma; ESGA, Excess Syndrome Group of Asthma; FVC, forced vital capacity; FEV1, forced expiratory volume at 1 s; PEF, peak expiratory flow rate; NS, no significance.
