Their bone ages were evaluated by Greulich-Pyle (GP), TW2 and CHN assessments, and the prediction of adult height (PAH) was evaluated by Bayley-Pinneau (BP), TW2-Ye and CHN methods. Their near final heights (NAH) were followed and compared with their PAH.

• 初诊时用GP、TW2、CHN法评估骨龄,用对应的BP、TW2-叶氏、CHN法预测成年身高(PAH),再与实测近似成年终身高(NAH)比较。
