- Each cell represents annual change in FEV1% pred/yr, unless otherwise indicated.
- Symbols: *:A positive number denotes a larger decline in FEV1% pred in women; a negative number denotes a large decline in FEV1% pred in men; †: Never smokers and former smokers were combined as non-smokers in the article since they did not differ in FEV1% pred decline.
