Scatter plot of correlation coefficient of flatness. (A) Scatter plots of the flatness positively correlated with the least axis length in the HC group (r = 0.325, P < 0.01). (B) Scatter plots of the flatness negatively correlated with the major axis length in the HC group (r = -0.263, P < 0.01). (C) Scatter plots of the flatness positively correlated with the least axis length in the TN group (r = 0.351, P < 0.01). (D) Scatter plots of the flatness negatively correlated with the major axis length in the TN group (r = -0.238, P< 0.01).
