Summary of the considerations for the interpretation of change in lung function
| Be aware of possible significant changes in lung function parameters over time (table 12) |
| Multiple measurements over time are more likely to signal a real change in lung function than two measurements |
| When too many indices of lung function are tracked simultaneously, the risk of false-positive indications of change increases |
| Clinical interpretation of serial tests should not be based solely on the coefficient of repeatability, but also on the clinical findings |
