<div>Findings demonstrated a pooled estimate of .82 for sensitivity and .83 for specificity for the RUDAS. Of note, there was variability between studies studies using different cutoff values, with the most common values of 22/23 and 23/24. Specific findings were as follows:</div> <ul> <li><span style="color: #333333;">Diagnostic performance did not differ significantly across socioeconomic levels (z= 0.63, p= 0.53) or between groups with different levels of formal education (z= -0.15, p=0.88).</span></li> <li><span style="color: #333333;">When compared with the Mini-Mental State Examination (MMSE), overall diagnostic performance did not differ significantly (z= -0.82, p= 0.41).</span></li> <li><span style="color: #333333;">Subgroup analysis revealed that, in low and middle income countries, the diagnostic performance of the RUDAS was significantly better than that of the MMSE (z = &minus; 2.02, p = .04).</span></li> </ul>

<div>Findings from five studies showed a pooled estimate of .80 for sensitivity and .79 for specificity for detecting MCI using the RUDAS.</div>
