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? Effects with effect year before 1998 pool to 0.254 SD versus 0.036 SD for effect year 1998 or later. → Shakeel 2024
