In [21] we address possible objections such as the influence between distance and number of products bought, which may invalidate the effect of the Product Sophistication.
(2008), and invalidates the effect of intentional attacks recently designed by Meerwald et al.
Furthermore, Chandra et al. (2001a) showed a correlation between metabolic activity and antifungal resistance in maturing biofilms, further invalidating the effect of growth rate.
If shown to be correct, this would invalidate the assumption that intervention effects are additive to placebo effects.
The latter monolithic alloy had a significantly higher corrosion resistance marked by Ca-addition, but the presence of carbon fibres in MMCs invalidated the beneficial effect of Ca. Carbon, as an electrically conductive element, is electrochemically unstable despite its almost chemical stability in aqueous chloride environments.
"Hinterland counties" within the still-regulated states, but farther away from the state borders, are used as a second control group to consider and reject the possibility that cross-border spillover of deregulation effects may invalidate the empirical design.
It is worth mentioning that such a feedback effect does not invalidate the conclusions of this study.
However, after provocation, there was an increase in NGF per milliliter of NAL and also a correlation with a high rhinorrohea score in the patient group; therefore, the dilution effect should not invalidate the results.
Theoretically, this boundary is expected to lie around the Planck mass (mP = ≈ ≈ ), where quantum effects are expected to invalidate the predictions of general relativity.
Thus, the potential differential carryover effects in the study could invalidate the analyses where the data from the two groups were combined.
