Subclaims¶
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.
q2 i? Treatment interaction analyses across demographic groups found effects that did not vary by subgroup, including racial background. → Weatherholtz 2024

q2 · i? · associational · r3
Moderation analysis within the same longitudinal panel study examined treatment interactions across demographic groups. The abstract reports "positive treatment effects that did not vary across demographic subgroups"; no interaction statistics or effect sizes are printed.
"We also examined possible treatment interactions across demographic groups. Using this approach, we replicated the previous findings and found positive treatment effects that did not vary across demographic subgroups"
