Fig. 2: The identified AUDIT/FTND-associated multimodal joint components in alcohol use and tobacco use groups.

The spatial brain maps of alcohol use (a) and tobacco use (c) were visualized at |Z| > 2. Correlation scatter plot between AUDIT (b), FTND (d) and the loadings of the identified component for each modality within alcohol use and tobacco use groups. IC refers to independent component. Asterisk (*) is used to indicate results which pass false discovery rate (FDR) correction for multiple comparisons.
