Fig. 3.

For each group, the mean body weight before surgery (PRE) and during the 4 weeks after surgery is presented. NGF infusion did not change the body weight of 23MO rats. Both 23MO groups showed decreased body weight during the 4 postoperative weeks, and this decrease was equal in both groups. 4MO-CON rats gained body weight in weeks 3 and 4, whereas 4MO-NGF rats showed a slight nonsignificant decline. Each point represents the mean body weight (± SEM) for each group for each week of testing.
