Cross-sectional areas (CSA) of the different fiber types in the diaphragm of the three groups. Propofol-anesthetized groups (either controlled mechanical ventilation [CMV] or spontaneous breathing [SB]) show the same levels of diaphragm fiber atrophy. White bar: control, light grey: CMV, dark grey: SB. *P < 0.05. CMV: n = 7; Con = control: n = 8; SB: n = 8; scale bar = 50 μm.
