  1. SE: spherical equivalent; SD: standard deviation; OR: odds ratio; CI: confidence interval; the first group was the reference group.
  2. Multiple OR*: adjusted for children’s age, gender, average parental refractive error, times spend on near work and outdoor, and item of eye exercises questionnaire; column 3 presented the OR (95% CI) of item of eye exercises questionnaire; column 4 presented the OR (95% CI) of item of children’s age.
  3. : significantly different as compared to the first group.
