^†Comparing the narrowly defined response of reasons of ‘health risks’ (n=18) with that of ‘legal risks’ (n=6) by U.S. verses non-U.S. status yields a p value=0.06 (Fisher’s exact test, two-tailed) or a p value=0.048 (Fisher’s exact test, one-tailed), based on an a priori expectation of a more frequently invoked legal rationale in the U.S. group.
