Among the six samples, the change in degree of fit (χ 2) was not significant after constraining factor loadings to be equal in males and females.
On the other hand, for both samples, the change in the intensity of the transmitted light of the tapered POF coated with ZnO nanostructures decreases linearly with relative humidity.
For the two considered samples the change of the non-specific contribution clearly dominates the observed change of the median chip intensity resulting in a stronger median signal of the scg-sample.
In the CVR and COPD samples the change in the number of days per week with more than 30 minutes of physical activity was positive and statistically significant (0.33 and 0.37 respectively).
As mentioned before, in both samples, the change in competence at T3 remains statistically significant, comparing with T0, despite the decline (except for SPs' assessment of the 2008 group, where, as mentioned earlier, no change reached statistical significance).
In spot samples, the change between P20 and P36 was +31 ± 9% (P = 0.0005) and 9 ± 10% (P = 0.4), respectively; which was a difference of 15% in the change adjusted for the ratio at P20, which was not significant (P = 0.1).
