	% Overlap	90.5	64.0	72.3
HDL	Overlap*	82	23	45
	% Overlap	73.2	56.1	57.7
LDL	Overlap*	30	147	13
	% Overlap	85.7	89.1	41.9
Total Cholesterol	Overlap*	3	135	12
	% Overlap	100.0	64.6	63.1

Amsterdam Born Children and their Development Cohort (dried blood spots)
		1st Quartile	2nd Quartile	3rd Quartile	4th Quartile
Triglyceride	Overlap*	36	32	32	44
	% Overlap	60.0	53.3	53.3	73.3
HDL	Overlap*	37	24	21	35

	% Overlap	58.3	35.0	33.3	56.7

Overlap* the number of samples with the measured and predicted lipid concentrations falling in the same quartile. Triglyceride ‘Desirable’ < 1.7 mmol/l, ‘Borderline’ 1.7–2.2 mmol/l, ‘Poor’ > 2.2 mmol/l, HDL ‘Desirable’ > 1.5 mmol/l, ‘Borderline’ 1.5–1.1 mmol/l, ‘Poor’ < 1.2.2 mmol/l, LDL ‘Desirable’ < 2.6 mmol/l, ‘Borderline’ 2.6–5.0 mmol/l, ‘Poor’ > 5.0 mmol/l, Total cholesterol ‘Desirable’ < 5.2 mmol/l, ‘Borderline’ 5.2–6.2 mmol/l, ‘Poor’ > 6.2 mmol/l
