Specify the exact number of experimental units allocated to each group, and the total number in each experiment. Also indicate the total number of animals used.
Examples
Example 1
“Treatment and transplantation received by the animals for each group. The group were named after the treatment they received in treatment phase 1 and 2: S = saline, L = L-DOPA thus, SS group received saline in treatment phase 1 and 2, SL group received saline in treatment phase 1 and L-DOPA in treatment phase 2, LS received L-DOPA in Treatment phase 1 and saline in treatment phase 2 and LL received L-DOPA in treatment phase 1 and 2. *These groups originally numbered 12 animals but some developed tumors unrelated to the experiment, so had be removed from the study.” [1]

"A total of 240 1-day-old Ross 308 male chicks were randomly allocated into eight equal groups with three subgroups of 10 birds each." [2]
