- 4/20/2020: We have uploaded diffusion weighted imaging (DWI) input data including DWI field maps for 5,635 subject's baseline MRI sessions. We are working with the NDA to get this data released publicly prior to 5/15/2020.

- 4/14/2020: We have uploaded raw fMRI task event files to the NDA for sessions among the 9,647 with task-based fMRI data. We are working with the NDA to get this data released publicly prior to 5/15/2020.

The `matched_group` field is the product of comparisons across site, age, sex, ethnicity, grade, highest level of parental education, handedness, combined family income, exposure to anesthesia, and family-relatedness which show no significant differences between the ABCD-1 and ABCD-2 groups. Comparison of the counts and means for each of these factors shows that ABCD-1 and ABCD-2 are negligibly different samples. Gender shows the largest absolute difference of 2.5 percent. No other demographic variables differ by more than 1 percent. See below table:
