Binary logistic regression analysis: the correlation between shock^a and early-onset thrombocytopenia

Variables	Early-onset thrombocytopeniab (platelet count < 100 × 109/Lc)			Early-onset thrombocytopenia (the drop decrease of platelet count was ≥ 25%d)
	OR	95%CI	P	OR	95%CI	P
Crude	2.952	1.534–5.681	0.001	2.090	1.242–3.516	0.005
Adjustede	2.709	1.359–5.398	0.005	1.900	1.113–3.243	0.019

Bold values show statistical significance of differences

^aShock patients require vasoactive medications

^bEarly-onset thrombocytopenia: thrombocytopenia occurrence within 6 days of linezolid treatment initiation

^cThrombocytopenia with platelet count < 100 × 10⁹/L and a decrease in 25% or more from baseline of the platelet count

^dThrombocytopenia due to a platelet count drop decrease of 25% or more from baseline

^eAge, hospitalization days, creatinine clearance rate, baseline platelet count were adjusted for in the regression model as the confounding factors
