Our leave-study-site-out cross-validation analysis (Table 2) confirmed the generalizability of the dGCN model to unseen data collected from different study sites of the ADHD-200 dataset. Replication analysis with independent samples collected using different study protocols will provide even stronger ...
ADHD PRSs were calculated based on a discovery dataset involving 38,691 individuals with ADHD and 186,843 controls [50]. Using SNP cutoff ofp < 0.50, the number of ADHD PRS SNPs was 99,330 with an associatedR2of ≈3.7%. For details, see Supplement. Statistical analyses Exploratory fact...
The current analyses also used cross-validation with an external test set to ensure that effects identified were replicable in an independent dataset. An additional weakness in the existing literature on the neurobiological basis of ADHD is a primary focus on categorical diagnoses of ADHD. There is...
3-D visualizations were completed in DSI studio (http://dsi-studio.labsolver.org/) (Yeh, 2021), an imaging dataset generated from 60 subjects were used (Yeh and Tseng, 2011). 3. Results and statistical analyses 3.1. Characteristics of the studies in the meta-analysis The literature search...
(Go,n = 200; 1000 ms duration), with an ISI jittered between 700 and 1000 ms. In 20% trials, interspersed in the stimulus sequence, a Go signal was followed by an upward arrow Stop signal (n = 60; 300 ms). The first Stop signal appeared 250 ms after a Go ...
Download: Download full-size image Fig. 1. The association between DRD2 genotype and SPN to lose varies by ADHD status. Figure depicts ERP grand average waveforms (positive up) for SPN to lose (scored in the −200-0 ms time window, at CPz, Pz, CP1, CP2, P1, and P2) across groups...
[145]. In case both parents participate in the assessments, data of the parent with the most complete dataset will be used for the ANCOVA, and if both are complete, the sex of the parent (or age, for same-sex parents) will determine which dataset will be used so that the fathers:...
Our dataset allowed us to evaluate performance in three tasks that measure executive function: i). The Flanker Task. The Flanker Task of Inhibitory Control and Attention is part of the EF assessments utilized in the NIH Toolbox- Cognition battery (http://www.nihtoolbox.org). This task measur...
We excluded one whole dataset from a participant who had an estimated IQ < 70. Our final sample’s demographic characteristics are summarized in Table 1. 2.3. Diffusion-weighted imaging acquisition, pre-processing, and quality control At W2, single-shell DWI data were acquired with a 1.5-...
