Multiple Logistic Regression Analysis of Associations between the Prevalence of Myopia (Defined as a Spherical Equivalent of Refractive Error of ≤-1.0 and Associated Factors in Senior High-School Students.

Abbreviation: TSNW, Time Spent for Near Work; DNW, Distance from Near Work*Model 1: Multiple logistic regression analysis using the step-wise backward method of testing associations between myopia and other parameters**Model 2: Multiple logistic regression analysis using the step-wise backward method of testing association between myopia, other parameters, and the interaction between sex and type of school, interaction between sex and family income per month, and the interaction between DNW and TSNW.***The dummy variable of TSNW1 = 1, if the observation was for 9–10.9h; the dummy variable of TSNW2 = 1, if the observation was for 11–12.9h; the dummy variable of TSNW3 = 1, if the observation was for 1≥13h.Multiple Logistic Regression Analysis of Associations between the Prevalence of Myopia (Defined as a Spherical Equivalent of Refractive Error of ≤-1.0 and Associated Factors in Senior High-School Students.
