Sensitivity and Subgroup Analyses
MYOPIA
Subgroup analyses comparing the efficacy of intervention for myopia prevention and control (incidence, SER changes, and AL changes) by different baseline SER groups and age groups were performed. Better efficacy was observed among children with an SER of 0.01 to 0.50 D than among those with an SER of −0.50 to 0.00 D (relative efficacy, 64.0% vs 14.0%; SER changes, 69.0% vs 39.8%; AL changes, 45.7% vs 23.4%) (
