Figure 2. Quercetin dietary enrichment transiently improved respiratory function in mdx mice .

Respiratory function was measured using whole‐body unrestrained plethysmography on alternating months throughout a 12 month study. A, respiratory frequency was increased throughout the testing period compared to mdx and was similar to C57. B–E, oral quercetin administration transiently improved tidal volume (B), minute ventilation (C), peak inspiratory flow (D) and peak expiratory flow (E). ^*Significantly different from C57; ^#significantly different from mdx. C57 (n = 7), mdx (n = 7), mdxQ (n = 6).
