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.
q3 i? In intent-to-treat HLM models, Standards 1-3 students in CREST treatment classrooms showed a statistically significant main treatment effect on the Engage in Behavior composite, with the treatment indicator explaining an additional 19.93% of intercept variance and 18.41% of slope variance. → Krystal M.

q3 · i? · causal · r2
Intent-to-treat hierarchical linear modeling of the cluster-randomized trial (12 CREST and 12 control schools) on the Standards 1-3 Engage composite. The article reports a "statistically significant main treatment effect" with 19.93% additional intercept variance and 18.41% slope variance explained.
"the final Engage model indicated a statistically significant main treatment effect. Adding the treatment indicator as a Level 2 predictor in the Engage ITT model explained an additional 19.93% of the variance in the intercept and 18.41% of the variance in the slope"

- Infant 1 and 2 students showed no statistically significant main or cross-level CREST treatment effects, which the authors attribute to low measurement reliability in ages 4-5 — related
- For Standards 1-3, the omnibus CREST score showed a positive but statistically non-significant treatment effect, and the mirrored Feel composite showed no significant effect — related
