Table 3 Risk ratio, adjusted risk ratio, and 95% confidence interval (CI) for development of airflow obstruction in 5 years.
From: Preserved ratio impaired spirometry with or without restrictive spirometric abnormality
Baseline spirometry category | Risk ratio | 95% CI | p value | Adjusted risk ratio* | 95% CI | p value |
|---|---|---|---|---|---|---|
No PRISm/airflow obstruction | 1 | 1 | ||||
Non-restrictive PRISm | 5.31 | 2.16–13.05 | < 0.001 | 4.47 | 1.66–12.01 | 0.003 |
Restrictive PRISm | 0.99 | 0.24–4.18 | 0.999 | 0.94 | 0.22–3.98 | 0.930 |
