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.

Wartime study by Galperin and Ginevskaia (1947) measuring arm-movement amplitude in 41 veterans with shoulder or elbow impairments across tasks differing in meaning. The article attributes to the authors that "they achieved up to 30% improvement in the experimental group as compared to the control group."

"According to the authors, they achieved up to 30% improvement in the experimental group as compared to the control group."
