Although there is some agreement on the statement above, the empirical evidence is still not robust, as different studies come to different conclusions, depending on the host countries being studied, the composition of immigrants, but most importantly, the statistical strategies and data each researcher uses to handle the research question.

Comparing the studies demonstrates that the results with respect to the individual MRI parameters vary widely, which can be caused by differing study designs as well as different study populations.
