Desktop software for PCs is available to generate predicted values, lower limits of normal and z-scores for spirometric indices for datasets containing up to 60,000 records. The input file must adhere to a strict format, so please read the instructions first:
The software serves 3 purposes:
- add predicted values, lower limit of normal, z-scores to up to 60,000 records ('Database conversion')
- obtain estimated coefficients for an ethnic group not covered in the Quanjer GLI-2012 equations ('New Ethnic Group')
- obtain mean z-scores for males and females for each of the spirometric indices ('Key Statistics')
