		DPM Score
Collage (%)	0	2	3	P-value
Total	0.667 ± 0.33^A	0.581 ± 0.17^A	0.648 ± 0.29^A	0.7724
Soluble	0.570 ± 0.31^A	0.431 ± 0.14^A	0.570 ± 0.19^A	0.3975
Insoluble	0.131 ± 0.03^B	0.147 ± 0.04^AB	0.265 ± 0.24^A	0.0374

Pectoralis major muscle associated with Pectoralis minor muscle with DPM score 0: unaffected, score 2: muscles with coagulative necrosis, fibrous tissue texture and necrotic area and score 3: with the damaged muscle tissue having a greenish appearance.
