I have an experiment with several factors. 1. The presence of the additive. 2. The presence of surgery 3. time factor.

sample experiment data below.

Rabbit groups

1. Control (C)

2. Control + additive. (CA)

3. Model operation. (MO)

4. Model operation + additive. (MO+A)

Blood sampling time: before surgery, 10 days after surgery, 30 days after surgery.

Example:

Before---------------------------------------10day---------------------------------30 day

С------CA-----M0 --MO+A---- С---A---MO -MO+A- ----------С--------A-----MO --MO+A

5,6a-7,2b -6,4c - 6,1d-------6,1e-6,4f-5,1b -6,3df------7,1abf- 7,3a--7,4bf -7,0ab

In the statistical program, I indicated the difference between groups in the time points (C, CA, MO, MO+A) as factor 1 and the difference between time points (before, 10 day, 30 day) as factor 2.. In the description of the two-factor analysis in the other articles, I see that they write a specific factor (drug, additives, operations). Since in the statistical program I indicated the difference between the groups, I can not describe the influence of the presence of the additive and operation separately.

Would it be correct to name the factors: the difference between groups at each time point, the difference between time points?
