Fig. 1: Temporal trends in autism research.
a The change in autism prevalence over time, based on data from [65,66,67]. Methodologies may differ between studies. b The changes in group-level standardized mean differences between autism and control samples over time, as described by Rødgaard et al. (2019) [14]. A significant downwards temporal trend was observed in five of seven investigated constructs in autism. c The number of published studies investigating autistic traits in the normal population and for other clinical conditions, showing an eightfold increase during the last decade. d The number of published empirical studies performing research on autism, showing a fourfold increase during the last decade.
