“…Additionally, Seeck, et al 15) had reported the diagnostic value of CGM based on two different methods in the same population, so only the better results for CGM were selected. Excluded studies: Nineteen studies were excluded after reviewing the original text for the following reasons: The population of the study was other than candidates for elective angiography (n = 6), including Poorzand, et al 27) in patients with psoriasis, Spiliopoulos, et al 28) in patients who received a heart transplant, Tölg, et al 29) and Khamis, et al 30) in patients with acute coronary syndrome, Herrmann, et al 31) in patients after revascularization, and Sadeghpour, et al 32) in patients with left bundle branch block (LBBB); lack of reporting required diagnostic value parameters that could be used to construct or calculate true positive (TP), false positive (FP), true negative (TN), and false negative (FN) results (n = 4); [33][34][35][36] different types of articles including case reports, narrative reviews or congress abstracts with insufficient diagnostic parameters (n = 6); [37][38][39][40][41][42] the reference standard for CAD diagnosis was other than CAD stenosis in angiography (n = 3), including Weber, et al who used 43) stress/rest myocardial perfusion scintigraphy and Birkemeyer, et al who used 44) MRI. Furthermore, the study of Brown, et al was also excluded due to the lack of reported sample size of patients with significant coronary stenosis; 45) however, the primary aim of this study was to assess the ability of CGM to detect physiologically significant coronary stenosis defined by fractional flow reserve (FFR).…”
