Variable importance analysis across three models. A–C The scatter plots depict the variable importance for the prediction of SE and onset of myopia and high myopia, respectively. The significance of the feature values varies depending on the variables being analyzed. In the “AMPR” variable, a high value indicates rapid progression of myopia between the first follow-up and baseline, and it is equivalent to NSE in the models. In “OSE” and “NSE”, a high value represents a low diopter, emmetropia, or even hyperopia, while a low value indicates severe myopia. For the “AGE” variable, high and low values correspond to older and younger ages at baseline, respectively
