Failure to account appropriately for the potential clustering effect of birth cohorts in the analysis of data from sequential cross-sectional studies may lead to misrepresentation of the data or, worse, to invalid statistical inferences on the significance of certain factors.
If residual spatial variation exists (an assumption that can be evaluated), then OLS estimates and corresponding tests of significance can lead to invalid results (Diggle et al. 1998a).

If such significance existed, the statistic was considered invalid.
One expert felt arterial blood pressure was relatively valid, another that it was relatively invalid and the third expert wasn't sure of the significance.
