有一段话，是FDA关于Bioequivalence的gudiance。我没有看明白。请大家帮助解释一下，先谢过。

[quote:1842b]
A subject-by-formulation interaction could occur when an individual is representative of
subjects present in the general population in low numbers, for whom the relative BA of
the two products is markedly different than for the majority of the population, and for
whom the two products are not bioequivalent, even though they might be bioequivalent
in the majority of the population.
