Intergroup comparisons of autistic features in FM only males < 13 years of age (a), < 19 years of age (b), < 37 years of age (c) and intellectual functioning in FM only males < 37 years of age (d), with broken lines representing CSS scores ≥ 4 (ASD cut-off previously reported for ADOS-2 [37]). p values for the intergroup comparisons were derived using the Wilcoxon rank-sum test. Black, dark and light grey dots represent the same participants between all four figures with FSIQ ≥ 70Back to article page
