Factors Affecting the Frequency of MA_KH ≥72 mm

	Clopidogrel‐Naïve		On Clopidogrel
	β	P Value	β	P Value
Sex	0.30	0.05	0.38	0.03
Diabetes mellitus	0.42	0.01	0.35	0.03
Beta blockers	0.2	0.1	0.36	0.02
Calcium blockers	0.28	0.04	0.2	0.07

Multiple logistic regression analysis (stepwise method) performed to examine the factors related to MA_KH as a categorical variable (with ≥72‐mm threshold). Nine variables were included in the logistic regression model based on the results presented in Tables 3 and 4: sex, race, diabetes, hypertension, beta blockers, calcium blockers, platelets, hemoglobin, and white blood cells. Shown in the table are only factors that were significantly associated with MA_KH ≥72 mm either on or off clopidogrel treatment. Race, hypertension, hemoglobin level, and white blood cell count were not significantly associated with the frequency of MA_KH ≥72 mm (P≥0.1). MA_KH indicates maximum thrombin‐induced platelet‐fibrin clot strength.
