Platelet count is a risk factor for infection

	Hazard ratio	Standard error	95% CI	P value
Platelet count	0.52	0.10	0.35–0.77	0.001
Platelet count Leucocyte count	0.54 1.10	0.11 0.04	0.37–0.79 1.01–1.19	0.002 0.021

Last platelet count before occurrence of infection was used. Platelets were grouped into groups per 20 × 10⁹/L. Cox regression analysis with platelet count as time-dependent variable was used. Secondary analysis was performed adding leucocyte count to the model
