Subclaims¶

q2 i? Time taken to read the utility bill improved significantly within the CCTV group but not within the eccentric viewing training group, with no significant between-group difference in change. → Leat et al. 2017

q2 · i? · causal · r2

Functional reading task modeled on Dougherty et al. (2009), with a two-minute upper time limit, in the same randomized trial. The article notes "the large variability in the amount of time taken at baseline is mostly due to one individual who read the bill very quickly."

"There was, however, a significant improvement in the amount of time taken within the CCTV group, but not within the eccentric viewing training group"
