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.

Growth curve analysis of M3L between 19 and 30 months with Expressive Vocabulary at 19 months as a predictor, shown in Fig. 5 with low and high vocabulary lines superimposed via median split. The introduction notes "Vocabulary size has been shown to be a strong predictor of later syntactic achievements".

Discussion¶
Related Claims¶
- Processing speed at 19 months does not significantly influence linear vocabulary growth between 19 and 30 months — related
- Faster processing speed at 19 months predicts faster syntactic growth between 19 and 30 months, controlling for concurrent vocabulary — related
- Processing speed at 19 months correlates with expressive vocabulary between 18 and 31 months, but processing speed at 25 and 31 months does not — related
