Fig 6 — Relationships between brain age delta and sleep measures using the unimodal (T1) and multimodal (T1+dMRI) IDPs. (A) $δ$ was significantly associated with PSQI using the unimodal T1 IDPs. (B) $δ$ was not significantly associated with WASO after applying FDR correction when the unimodal T1 IDPs were used. (C) $δ$ was significantly related to PSQI with the multimodal (T1+dMRI) IDPs. (D) $δ$ was not significantly associated with WASO when the multimodal (T1+dMRI) IDPs were used. All relationships between brain age delta and sleep measures are FDR-corrected for multiple comparisons set at p < 0.05. Note that the raw PSQI and WASO scores are square root and log-transformed, respectively (see Section 2.2).
