Note: Grades change is the changes in average GPAs in core subjects from the 1st to 2nd marking period in 9th grade. Values lower than 0 indicate grades declines, whereas values above 0 correspond with grades increases. Cortisol (nmol/l) values are scaled at raw means and standard deviation after data trimming and transformation.
