1.A doctor conducted a diagnostic test of plasma oxidized low-density lipoprotein (Ox-LDL) on 200 patients with coronary heart disease and 300 normal people, and coronary angiography was the "gold standard". Ox-LDL level 245.8U/L was regarded as the positive cut-off value for diagnosis. The results are shown in the table below. Table 1 Ox-LDL diagnostic test results of 200 patients with coronary heart disease and 300 normal people coronary angiography coronary heart Diagnosed Ox-LDL level (245. 8U/L) total normal disease 150 100 250 50 200 250 total 200 300 500 Please calculate sensitivity, specificity, positive predictive value, negative predictive value, Youden index.
