Correlation and agreement analysis of BA values assessed by the three radiologists applying the Greulich-Pyle method and chronological age values. a Pearson product-moment correlation demonstrates significantly lower correlation with r = 0.842, 95% confidence interval (CI) 0.803–0.902, and r2 = 0.760, 95% CI 0.725–0.804, compared to the correlation between values based on the software and chronological age values (p < 0.001). b Bland-Altman plot also shows lower agreement between BA values assessed by the three radiologists applying the Greulich-Pyle method and chronological age values compared to the agreement between values based on the software and chronological age values (p < 0.001). Values are given in years. BA Bone age, GP Greulich-Pyle
