Gait, femoral cortical bone and muscle mass are preserved in aspartame-fed animals. (A) Gait variations for aspartame-fed animals and controls. Aspartame-fed and control digitized density values obtained from periodical radiographs of individual animals. (B) Differences in average curves of femoral cortical bone density for the aspartame group (solid line, squares for individual values) and controls (dashed lines, crosses for individual values) are statistically significant (P-value of 0.001). (C) Differences in average curves of femoral muscle mass for aspartame group (solid line) and controls (dashed lines) are statistically significant (P-value of 0.006).
