Influence of coagulation parameters on bleeding rates

	Platelet count	Quick test	PTT
Reference range	≥ 70,000/μl	≥ 70 %	< 50 s
Findings in relation to biopsy	42.5% (n = 948)	43.4% (n = 968)	34.8% (n = 775)
Biopsy in patients not meeting full coagulation criteria	1.2% (n = 11)	5.1% (n = 49)	1.4% (n = 11)
Most significant deviation from reference range	32,000/μl	45%	66 s
OR [95%-CI]	1.000 [0.997-1.004]	0.970 [0.0943-0.999]	1.078 [1.014-1.146]
p-value *	0.8301	0.0430	0.0157
