Correlations between area under curve (AUC) and various biochemistry parameters in the two compression groups
Correlation coefficient	AUC/PI	AUC/CK	AUC/LDH	AUC/MDA	AUC/MPO
AUC in the 2-h compression group (n = 61)
r	0.97	0.83	0.84	0.82	0.70
p-value	<0.001	<0.001	<0.001	<0.001	<0.001
AUC in the 4-h compression group (n = 59)
r	0.97	0.73	0.77	0.81	0.63
p-value	<0.001	<0.001	<0.001	<0.001	<0.001

CK, creatine kinase; LDH, lactate dehydrogenase; MDA, malondialdehyde; MPO, myeloperoxidase; PI, peak intensity.
