Fig. 3From: Artificial intelligence in bone age assessment: accuracy and efficiency of a novel fully automated algorithm compared to the Greulich-Pyle methodCorrelation and agreement analysis of BoneXpert version 2.1-derived BA values and the reference values. a Pearson product-moment correlation shows excellent correlation with r = 0.988, 95% confidence interval (CI) 0.971–0.998, and r2 = 0.976, 95% CI 0.951–0.992. b Bland-Altman plot demonstrates excellent agreement between BA values of both approaches. Values are given in years. AI Artificial intelligence, BA Bone ageBack to article page
