Distribution of male-to-female participant ratio for studies (N = 69) that reported positive versus negative findings pertaining to sex/gender-by-diagnosis interaction effects and sex/gender-stratified autism-control differences. The distribution of male-to-female participant ratio is shown here for all autism groups, control groups, and overall sample (total). The neuroimaging studies that reported a negative/non-significant finding appear to have larger male-to-female participant ratio with much greater spread especially for the autism group in comparison to the studies that reported positive/significant finding.
