In addition to analyzing discriminability, which controls for any response bias, we also further confirmed all main findings with analyses of accuracy.
No differences in frequencies of genotypes or alleles between cases and controls for any polymorphism individually were found by χ2 analysis (p = 0.444, p = 0.507 and p = 0.662, respectively).
The inclusion of student fixed effects controls for any between-student variation that is constant over time, such as innate ability, gender, etc. School fixed effects control for time-invariant differences across the schools.
