Fig 1.
The SALIA collective at baseline (1985–1994) and follow-up examination (2008/2009 and 2012/2013).
Table 1.
Description of the study characteristics of the healthy never-smoking women (HNSW) at baseline and follow-up examination.
Table 2.
Comparison of baseline characteristics of healthy never-smoking women (HNSW) lost to follow-up and available at follow-up.
Differences in the continuous variables were tested with the two-sample t-test and differences in the categorical variables were tested with Fisher’s exact test at the 5% significance level.
Table 3.
GLI-based z-scores of all healthy never-smoking women (HNSW) grouped by time of examination (baseline and follow-up).
Two one-sided tests for equivalence were performed to establish equivalence between the mean z-score of the GLI reference population and SALIA (p<0.05).
Fig 2.
Comparison of measured SALIA values (HNSW) for FEV1, FVC and FEV1/FVC with height-adjusted predicted means of the GLI reference values and older NHANES III and ECSC reference values (n = 299).
Table 4.
The longitudinal validity of the GLI reference values. Difference between z-scores at baseline and follow-up (zf − zb).
Two one-sided tests for equivalence were performed to establish equivalence between the mean z-scores of the GLI reference population and SALIA.
