Analysis of the thoracic anteroposterior length ratio in C57 and C3H mice. (A) The thoracic anteroposterior length ratio in C57 mice was gradually decreased with age in the development stage. (n = 5) (B) C57 mice exhibited significantly lower thoracic anteroposterior length ratios than C3H mice (n = 8) (C) Representative X-ray images of the sternum and thoracic vertebrae from C57 mice at postnatal 2 and 4 months. (D) Scatter plots illustrate that no scoliosis was developed during the development stage in C57 mice (n = 15). Values are the mean ± SD. ***P < 0.001 compared with C3H mice.

SD = standard deviation.
