Selection criteria and participant numbers in the two Amblyopia Treatment Studies (ATS), ATS5 and ATS13. The studies are similar until the end of the OTA phase, and diverge thereafter. However, this analysis focuses on gains up to the end of the OTA phase and thus the results from ATS 5 and ATS 13 are combined. Total participants n = 280 [(nATS5= 152) + (nATS13= 128)]. Data sets for both studies are available on the PEDIG website [11]
