CCTV produced much larger percentage increases in reading speed (86% for 1.3M, 74% for 1M) than eccentric viewing training (16%, not significant)¶

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.
q2 i? The trial's percentage gains in reading speed favored CCTV over eccentric viewing training, consistent with prior studies the article cites. → Leat et al. 2017

Authors' discussion of the trial's descriptive percentage changes, noting the CCTV gains "are similar to those found by Peterson et al. (2003)"; the article also reports a 16% non-significant increase with eccentric viewing training for 1.3M print.
"compared to an 86% increase with CCTV for 1.3M and 74% for 1M print. These increases with CCTV are similar to those found by Peterson et al. (2003), who reported that reading with a stand-mounted CCTV was 73% faster than with an optical aid."

Learner Variables¶
- Reading Fluency — outcome: instruction changes it
