Mean differences in sCD40L levels among ACS subgroups.

ACS (I)	ACS (2)	Mean difference (I–J)	P value
Normal	STEMI	−38.83514*	.001
	Non-STEMI	0.38018	.976
	Unstable	4.95039	.688
STEMI	Non-STEMI	39.21531*	.000

Non-STEMI	Unstable	4.57021	.702

Mean difference (I–J): The difference in mean sCD40L levels between the 2 ACS subgroups. P value indicates the statistical significance of the mean differences.

ACS = acute coronary syndrome, STEMI = ST-elevation myocardial infarction.

^* The mean difference is significant at the .05 level.
