3. In-hospital clinical outcomes in the propensity score-matched cohort.

	Non-thrombocytopenia (n = 167, DPC ≤ 50%)	Thrombocytopenia (n = 167, DPC > 50%)	P-value	Adjusted OR	95% CI	P-value
Data are presented as n (%). *Presented as median (interquartile range). CI: confidence interval; DPC: drop in platelet count; ICU: intensive care unit; LOS: length of stay; OR: odds ratio.
