Pineal gland volume is associated with prevalent and incident isolated rapid eye movement sleep behavior disorder

Figure 2. (A) Diagnostic accuracy for prevalent probable REM sleep behavior disorder (pRBD) at the baseline evaluation and (B) predictive accuracy for incident pRBD at the 2-year follow-up evaluation of the baseline pineal parenchyma volume (VPP, mm3) and pineal gland volume (VPG, mm3). Abbreviations: AUC = area under the receiver operator characteristic curve; CI = confidence intervals.
