It is a game of mathematics! OK, let's say, if you had 100 apples at the beginning, then you lost 50, only 50 in your hand. We can say that your apples now only 10% of your original quantities. Or, if you want to say, how many times did you get your decrease of your apples comparing with your original? It should be 2 time decrease (¼õÉÙÒ»±¶ or ÔÀ´ÊÇÏÖÔڵĶþ±¶£¬100/50=2)£® Right? OK, so far so good. Let's put it in your case. For your case, you can use 2^-¡÷¡÷CT directly and put your results there, the last one is 0.1285. But if you want to say in another way (like the apple case above), how many times your sample decrease comparing with your non-treatment, you could not say 0.1285, it display as -(1/x). Here 1/x means the number of times you compare your treatment with your non-treatment. "-" means that is a decrease. 1/0.1285=7.8, so it means your original group is as 7.8 times much as your 48hr treatment samples. It always happens when we want to emphasize the importance of something. If you say after 48 hours, the target decrease to 0.1285 of the control group, it sounds not as that kind of shock effects as the target decrease around 7 times (7.8-1). We have to admit that sometimes (maybe always) how to display your data even more important nowadays. Hope it helpful.
