Findings demonstrated a pooled estimate of .82 (95% CI, .78–0.86) for sensitivity and .83 (95% CI, .78–.87) 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:<br />
<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 = − 2.02, p = .04).</span></li>
</ul>
Findings from five studies showed a pooled estimate of .80 (95% CI, .58–.92) for sensitivity and .79 (95% CI, .63–.89) for specificity for detecting MCI using the RUDAS.
