Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? DTI metrics (FA, MD, AD, RD) showed no significant group differences in any delineated tract, even uncorrected. → Bulthé Jessica 2019
Evidence¶
Bulthé Jessica 2019¶
Bulthé Jessica, Prinsen Jellina, Vanderauwera Jolijn, Duyck Stefanie, Daniels Nicky, Gillebert Céline R., Mantini Dante, Op de Beeck Hans P., De Smedt Bert. (2019). Multi-method brain imaging reveals impaired representations of number as well as altered connectivity in adults with dyscalculia. Neuroimage, 190, 289-302. https://doi.org/10.1016/j.neuroimage.2018.06.012
q3 · i? · associational · r2
Deterministic tractography (ExploreDTI/TrackVis) in 23 controls and 21 participants with dyscalculia; FA, MD, AD and RD were extracted for corpus callosum, IFOF, ILF and arcuate tracts with FDR correction across tracts; e.g. FA t-values ranged from −1.85 to 1.41.
"None of the tracts under investigation showed a significant group difference (even at uncorrected level for multiple comparisons) for fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD) values."
