Ln(SDF-1) quartiles	Quartile 1* (n=424)	Quartile 2* (n=438)	Quartile 3* (n=383)	Quartile 4* (n=358)	p-value per quartile increment in ln(SDF-1)	p-value† per 1 SD‡ increment in ln(SDF-1)
CD 34+ (% of CD34+ cells in peripheral blood excluding red blood cells, platelets and cell debris) [95% CI]
Model 1	0.081 (0.077–0.085)	0.076 (0.073–0.080)	0.075 (0.070–0.079)	0.073 (0.069–0.077)	0.01	0.02
