Table 1 Studies comparing cardiovascular morbidity and mortality in elderly with pre-diabetes and normal glucose tolerance

Ref.	No. of participants	Age at inclusion	Length of follow up (yr)	Population	Results
Kowall et al[9]	1466	55-74	8.8 (median)	German	Mortality rates were almost equal in the pre-diabetes and NGT groups
Schöttker et al[10]	8365	50-74	7.9 (median)	German	Major CV event1 rates were almost equal in the pre-diabetes and NGT groups
Deedwania et al[11]	4602	≥ 65	13 (median)	United States: 87% Caucasians, 13% African American	Major CV event2 rates were almost equal in the pre-diabetes and NGT groups

¹Major cardiovascular events including non-fatal stroke, non-fatal MI and cardiovascular mortality;
