The chronological age of the participants was calculated using their date of birth. Data were analyzed by paired t-test and Pearson&rsquo;s correlation coefficient (alpha=0.05). The intra-examiner reliability was analyzed using the Cohen&rsquo;s kappa.</span></span></span>&nbsp;</span></span></span><br> <span style="font-size:13pt"><span style="line-height:105%"><span style="font-family:&quot;Times New Roman&quot;,serif"><b><span style="font-size:9.0pt"><span style="line-height:105%"><span style="font-family:&quot;Verdana&quot;,sans-serif"><span style="color:#2e74b5">Results: </span></span></span></span></b><span style="font-size:9.0pt"><span style="line-height:105%"><span style="font-family:&quot;Verdana&quot;,sans-serif"><span style="color:#0e101a">A statistically significant difference existed between the chronological age and the age estimated using the London Atlas method (t-value=-8.301, P<0.05). A positive statistically significant correlation was found between the estimated age using the London Atlas method and the chronological age in all age groups (Pearson&rsquo;s correlation coefficient of 0.989 in males and 0.985 in females, P<0.05). The goodness of fit evaluation of the London Atlas method for prediction of actual age indicated that the model can fit with R2 value of 0.975.</span></span></span></span><span style="font-size:9.0pt"><span style="line-height:105%"><span style="font-family:&quot;Verdana&quot;,sans-serif"></span></span></span></span></span></span><br> <span style="font-size:13pt"><span style="line-height:105%"><span style="font-family:&quot;Times New Roman&quot;,serif"><b><span style="font-size:9.0pt"><span style="line-height:105%"><span style="font-family:&quot;Verdana&quot;,sans-serif"><span style="color:#2e74b5">Conclusion:</span></span></span></span></b> <span style="font-size:9.0pt"><span style="line-height:105%"><span style="font-family:&quot;Verdana&quot;,sans-serif"><span style="color:#0e101a">The London Atlas method showed a strong positive correlation with actual chronological age while at the same time a statistically significant difference existed between the actual age and estimated age.
