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? The WWC had reservations about the Cal-Learn randomized controlled trial because second-survey exclusions depended on conditions potentially affected by the incentives, threatening group equivalence. → Financial Incentives for Teen Parents to Stay in School 2006

q2 · i? · review · r2
WWC research review of the Cal-Learn randomized controlled trial (Mauldon et al., 2000). Beyond low response rates, the report states sample members "were excluded from the second survey based on conditions that could have been affected by the financial incentives," so remaining groups may no longer have been equivalent.
"the WWC had reservations about the study because sample members were excluded from the second survey based on conditions that could have been affected by the financial incentives, such as high school completion within six months of random assignment"
