†40 individuals with ASD and 58 controls were included in the global segmentation analysis. After quality-check, 37 individuals with ASD and 56 controls were included in the anterior lobe analysis; 37 individuals with ASD and and 58 controls were included in the Crus I/Vermis analysis. In the eye-tracking analysis, 33 indviduals with ASD and 26 controls were included (See Supplementary Material 2 for full Table).
*Data for BNI missing (different versions of the ADOS scores (total of communication and social interaction subscores) that could not be computed in the same mean).
**Data missing for 31 individuals with ASD (but global IQ > 70) or IQ > 85 (−1 DS) assessed with the Kaufman Brief Intelligence Test-2 (KBIT2) in the BNI center and the National Adult Reading Test (NART) in Créteil (France).
