The age and body weight of uninjured, control rats and C2HS rats at 2-, 4-, 8- and 12-week post-injury

Group	Age (days)	Body weight (g)
C2HS rats were injured at 3 months of age, and therefore the post-injury measures were obtained at different ages. Breathing patterns in C2HS rats were compared to rats of similar body weight (Fig. 3).
2-week weight control	85±4	300±5
4-8-week weight control	106±l	355±2
12-week weight control	108±2	450±4
2-week post-C2HS	105±4	293±8
4-week post-C2HS	124±2	345±14
8-week post-C2HS	149±3	354±16
12-week post-C2HS	155±4	452±13
