Table 1 Overview of analysis strategies

From: Network-specific sex differentiation of intrinsic brain function in males with autism

Strategy Description of overlapping maps Addressed potential confounds Samples
Strategy 1
Originally published Z-maps
Z-maps obtained from original ABIDE I and FCP samples ABIDE I: N = 763 (ASD = 360; NT = 403)
FCP: N = 828 (NT M = 357; NT F = 471)
Strategy 2
Adjusting analytical pipelines
Z-maps obtained after aligning processing with samples similar to strategy 1 Differences in MRI analytical methods (i.e., preprocessing and group model) ABIDE I: N = 759 (ASD = 356; NT = 403)
FCP: N = 824 (NT M = 356; NT F = 468)
Strategy 3
Adjusting age
Z-maps obtained in age-matched ABIDE I and FCP subsamples Differences in sample age and MRI analytical methods ABIDE I: N = 199 (ASD = 93; NT = 106)
FCP: N = 439 (NT M = 183; NT F = 256)
Strategy 4
Independent NT sample
Z-maps of ABIDE I subsample as strategy 3 and an independent sex difference sample from Brain Genomics Superstruct Project (GSP) Differences in sample age and MRI analytical methods ABIDE I: N = 199 (ASD = 93; NT = 106)
GSP: N = 742 (NT M = 320; NT F = 422)
