Results of the comparison of summary receiver operating characteristic analyses between diagnostic tests

	Reference test
	Ambulatory electrocardiography	Exercise electrocardiography	Radionuclide ventriculography	Myocardial perfusion scintigraphy	Dobutamine stress echocardiography
The figures indicate relative diagnostic odds ratios for comparison between the reference test in the column v the test in the row; the relative diagnostic odds ratio indicates the diagnostic performance of a test, with a value larger than 1 indicating better discriminatory power, a value equal to 1 no difference, and values below 1 corresponding to reduced discriminatory ability. Figures in parenthesis are the 95% confidence intervals.
