[求助] 有做动物实验的大神吗?能帮我看看这篇论文的动物分组问题吗?

Animal pairs were pseudorandomized into one of five conditions: Sham—
control diet (n=5); Sham—high fat, high sugar diet (HFS; n=6); 2-vessel
occlusion—control diet (2VO; n=8); 2VO-HFS diet (n=10); and 2VOt
PA/CA (n=11). Animals in the Sham, HSF, 2VO, and 2VO-HSF groups were
housed in pairs and a single condition was represented within a cage. The
PA/CA condition consisted of a paradigm previously used in our
laboratory3 and was implemented after 2VO surgery (Experiment 2).
Animals in this condition were individually exposed to voluntary running
wheels, 3 days/week and on alternate days were housed in pairs
and exposed to cognitive activity, 3 days/week; the seventh day they
were housed in pairs in the absence of PA or CA. Physical activity consisted
of exposure to 36 cm diameter wheels for 24 hours a day. Cognitive activity
consisted of modified Hebb–Williams maze (10010020 cm3),14 for
24 hours a day, with the maze configuration changed weekly to increase
novelty. Additionally, novel objects and food rewards were scattered
throughout the maze and the water bottle and food hopper
were separated to encourage exploration. The PA/CA animals were
housed in these conditions throughout the study. The PA/CA animals
were housed in these conditions throughout the study except during
behavioral testing and pair-housed in standard cages on the remaining
day each week.

我查资料即使采用伪随机数分组,但是每组动物数量最起码是相等的呀,但是这篇论文好像是每组数量都是随机的。而且 Sham—control diet (n=5)的组数少于6,不是说是要具有统计学意义,数据个数不能少于6吗?求大神帮忙解惑!!!!
