Values are expressed as means ± standard error. ^aAdjusted for age, sex, baseline spherical equivalent, number of myopic parents, and outdoor time unless stratified by that factor. ^bP value tests for group difference. ^cP value tests for the interaction between treatment and baseline characteristics. ^∗Significant at 0.05.
