Spirometry | Group (1) (n = 89) | Group (2) (n = 111) | X2 | P value |
|---|---|---|---|---|
Normal | 11 (12.4%) | 73 (65.8%) | 57. 8 | < 0. 001 |
Reversible obstructive | 78 (87.6%) | 0 (0.0%) | Fisher | < 0.001 |
Irreversible obstructive | 0 (0.0%) | 20 (18%) | Fisher | 0.003 |
Restrictive | 0 (0.0%) | 10 (9%) | Fisher | 0.01 |
Mixed | 0 (0.0%) | 8 (7.2%) | Fisher | 0.02 |
