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.

q2 i? No gene polymorphism was significantly associated with GPA in the initial regression on the genetic subgroup. → Imlach 2017

Evidence

Imlach, A.-R., Ward, D. D., Stuart, K. E., Summers, M. J., Valenzuela, M. J., King, A. E., Saunders, N. L., Summers, J., Srikanth, V. K., Robinson, A. & Vickers, J. C. (2017).

q2 · i? · associational · r2

In the initial multiple regression on the genetic subgroup (N = 181), none of APOE, BDNF Val66Met, KIBRA, COMT Val158Met or SERT 5-HTTLPR significantly predicted GPA (all p > 0.15 in Table 2). The authors conclude a candidate gene approach to predicting later-life academic success may not succeed.

"as the initial regression identified that no gene polymorphism was significantly associated with GPA, a separate hierarchical multiple linear regression was conducted within the full sample"
