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? Pre-COVID data and supplementary datasets showed a linear six-month increase of 4.30 SLS raw score units, uniform across initial fluency levels and test versions, explaining 98.2% of variance in mean raw scores. → Kraus 2024

Kraus, E. B., Wild, J., Schilcher, A., & Hilbert, S. (2024). Exploring the Short-Term and Long-Term Effects of the COVID-19 School Closures on Reading Fluency in Southern Germany: A Longitudinal Causal Effects Analysis. https://osf.io/bu2ad/
q3 · i? · causal · r2
Pre-trend estimation via hierarchical linear regression on the study sample plus SLS norm samples and low-performer data from Peters et al. (2021). The text reports "an average six month increase of 4.30 raw score units" and that a linear time effect and random intercept explained 98.2% of variance in mean raw scores.
"Pre-COVID data indicated a linear development of SLS raw scores with an average six month increase of 4.30 raw score units, as displayed in Figure 2."
