Bold values indicate statistical significance p ≤ 0.05.

SFCT subfoveal choroidal thickness, CHSQ score the score of Children’s Sleep Habits Questionnaire, Ref reference group.

aThe multivariable model was adjusted for age, gender, AL, height and birthweight.

bThe regression coefficient B is standardised regression coefficient.
