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? The UPC group met developmental expectations for word reading accuracy and fluency but performed poorly on reading comprehension, on average one to two standard deviations below developmental expectations. → Li 2018

Discussion characterization of the UPC group (n = 216) defined by regressing SRI comprehension onto decoding and word recognition measures. The group is described as fitting the Simple View of Reading, with poor comprehension driven by poor language comprehension.

"The sample of subjects with UPC in our study had average to above average word-level reading skills, but performed poorly on reading comprehension, on average one to two standard deviations below developmental expectations."
