Correlation and agreement analysis of bone age values assessed by the three radiologists applying the Greulich-Pyle method and the reference values. a Pearson product-moment correlation shows significantly lower correlation with r = 0.901, 95% confidence interval (CI) 0.872–0.934, and r2 = 0.812, 95% CI 0.762–0.854, compared to the correlation between values based on the software and the reference values (p < 0.001). b Bland-Altman plot also demonstrates lower agreement between values assessed by the three radiologists applying the Greulich-Pyle method and the reference values compared to the agreement between values based on the software and the reference values (p < 0.001). Values are given in years. GP Greulich-Pyle
