From: A predictive nomogram: a cross-sectional study on a simple-to-use model for screening 12-year-old children for severe caries in middle schools

Fig. 1

The nomogram constructed for identifying severe caries was based on multivariate logistic regression. This model is quite simple to use. For example, if a child is in an urban population, a vertical line is drawn where the region of the nomogram is “urban”, and the corresponding points are approximately 60 points. Similarly, suppose this child satisfies the conditions of “Female”, “Middle level of urbanization”, “Non-only child”, “Very poor oral health for self-assessment” and “never visits dentist”, and the scores are “48, 0, 20, 100, 0” respectively. In this case, the total points are 228, and the corresponding risk value is between 0.2 and 0.3
