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.
q4 i2 In Wills et al. (2016), the percentage of time displaying disruptive behaviors was 7.01 in CW-FIT classes versus 15.72 in comparison classes (effect size 1.00, improvement index +34, p<0.01). → wills-2016-disruptive
