B, F Lipid subclasses in LD muscles under positive and negative ion modes. C, G Principal component analysis of the confirmed lipids in LD muscles under positive and negative ion modes. D, H Orthogonal partial least squares discriminant analysis of the confirmed lipids in LD muscles under positive and negative ion modes. n = 10–11 for each group
