Abbreviations: AL, axial length; D, diopters; SER, spherical equivalent refraction.
a
The intervention group included those who continued the intervention and those with interrupted intervention.
b
Absolute efficacy = value in control group − value in intervention group; relative efficacy = (value in control group − value in intervention group)/value in control group.
c
Difference of efficacy = the efficacy difference between 2 subgroups.
