Fig. 3: Factors independently associated with ortho-k lens use and unsatisfactory CVA.

From: The rate of orthokeratology lens use and associated factors in 33,280 children and adolescents with myopia: a cross-sectional study from Shanghai

Forest plots of binary logistic regression model and its results with ortho-k lens use (a) and unsatisfactory CVA (b) as dependent variables respectively. The selection of variables considered both statistical results and clinical significance. BMI body mass index, D dioptre, CVA corrected visual acuity. *P < 0.05 was considered statistically significant. aThe correction target of ortho-k lenses was defined as the sum of the spherical power plus half of the cylindrical power of the lens.
