Regression estimates of the main analyses and their confidence intervals. L left, ALL whole sample, MZ within monozygotic twins, DZ within dizygotic twins. Note that although none of the associations survived correction within the MZ sub-sample, the confidence intervals cross the zero line only for the association between autistic traits and the L hippocampus—L fusiform gyrus connection. The forest plots were created in RStudio3.5.1, using the package “forestplot”. Examples of the according connections in a single participant (right side) were created using functions within the NORA platform (http://www.nora-imaging.com).
