Death rate ratios (RR) and 95% confidence level (CL) across hemoglobin categories >10 g/dL stratified according to absence or presence of relative thrombocytosis (platelet count < or ≥300 ×10³/υl).

A. Blood platelet count <300,000 (n= 34,573)
Hemoglobin categories (g/dL)	Minimally adjusted		Case-mix adjusted
	RR (95% CL)	P-value	RR (95% CL)	P-value
10–10.99	1.43 (1.36–1.52)	<0.001	1.46 (1.38–1.55)	<0.001
11–11.99	1.12 (1.07–1.17)	<0.001	1.12 (1.07–1.17)	<0.001
12–12.99 (reference)	1.0	n/a	1.0	n/a
≥13	1.03 (0.97–1.09)	0.4	1.04 (0.99–1.10)	0.1

B. Blood platelet count ≥300,000 (n=6,214)
Hemoglobin categories (g/dL)	Minimally adjusted		Case-mix adjusted*
	RR (95% CL)	P-value	RR (95% CL)	P-value
10–10.99	1.55 (1.37–1.75)	<0.001	1.62 (1.43–1.84)	<0.001
11–11.99	1.25 (1.11–1.40)	<0.001	1.31 (1.17–1.47)	<0.001
