Clinical characteristics	High levels of Capn4	Low levels of Capn4	P	Molecular characteristics	High levels of Capn4 (no.)	Low levels of Capn4 (no.)	P
Age (year)			0.549	MIB‐1			0.47
Median	52	54		High	22	17
Range	13–77	13–77		Low	30	25
Sex (no.)			0.636	TP53			0.38
Male	32	27		Mutated	22	19
Female	20	15		Wild‐type	30	23
Preoperative KPS (no.)a			0.873
≥70	47	39
