Fig. 3

Comparison of diaphragm thickness between the standard-protein Group and High-protein group. (A) The diaphragm thicknesses of two groups on day 1, 5, and 10. (B) The diaphragm atrophy ratio on day 5 and day 10, as comparing to the diaphragm thickness on day 1. Data are presented as mean ± SD. “Asterisk” indicates a significant difference between the two groups (p < 0.05)
