Consideration of the sample in question is necessary for proper screen selection. See reference list for numbered studies. Rounded to nearest whole value. Ordered with balance of highest sensitivity and specificity. NP = neuropsychological. IR = Impairment rate. Accuracy = overall correct classification accuracy. ‘-‘ = not reported. Sensitivity refers to the proportion of individuals identified as impaired on both the gold standard and the screen. Specificity refers to the proportion of individuals identified as unimpaired on both the gold standard and the screen. HAD = HIV Associated Dementia. MND = Mild Neurocognitive Disorder. HVLR-R = Hopkins Verbal Learning Test, revised. ndGP = nondominant hand Grooved Pegboard. Cod = Coding. ^a manually calculated; ^b values reported; ^c sample excluded ANI category
