Table 4. Example table: net reclassification improvement based on addition of gene count score to Framingham offspring risk score.

	Framingham offspring risk score plus gene count score				Reclassified
Framingham offspring risk score	<5%	5–10%	10–15%	>15%	Increased risk	Decreased risk	Net correctly reclassified
People without diabetes during follow-up
<5%	2295	48	0	0
5–10%	36	482	43	0	121	64	−1.7%
10–15%	0	19	181	30
>15%	0	0	9	181
People with diabetes during follow-up
<5%	52	8	0	0
5–10%	2	37	3	0	14	11	1.5%
10–15%	0	4	24	3
>15%	0	0	5	64
Net reclassification improvement −0.2% (95% CI −5.1 to +4.7); P=0.94.
