Form 2728Clinical Data
aRows are ordered by descending sensitivity. n = the number of cases of each condition identified by the medical record review. “Any CVD” combines CAD, CVA/TIA, MI, and PVD into a single definition (not defined as such on Form 2728). Sensitivity and specificity were calculated using the CHOICE data as the reference group. 95% CI values are binomial exact. The difference between Form 2728 and clinical data prevalence was tested using the McNemar χ2 test for paired observations. For 2 × 2 tables with cells with fewer than 10 observations, the McNemar exact test was used. CI, confidence interval; CVD, cerebrovascular disease. Other abbreviations as in Tables 1 and 2.
