To do a follow-up sonography assessment of the thymic size in infants at an age of 24 months, and to create a longitudinal prediction model for the thymic index covering all ages from birth to 24 months.
Of 37 infants examined in an earlier investigation, 34 attended a 24-month follow-up examination. The thymic index, a volume estimate, was assessed by sonography and compared to clinical variables, breast-feeding status and illness. The longitudinal prediction model was based on data throughout 2 years.
There was no significant relation between the thymic index and the clinical variables, breast-feeding status or illness at 24 months. An overall test for the effect of breast-feeding status at 4 months for infants from 0-24 months was significant, as was the actual body length of the infants from 0-8 months. Prediction models were estimated.
Based on a 24-month longitudinal sonography study, prediction models are presented whereby the thymic size, as an index, can be predicted at all times from birth to 24 months of age.
对24个月大的婴儿进行胸腺大小的超声随访评估，并建立一个涵盖从出生到24个月所有年龄段的胸腺指数纵向预测模型。
在早期调查中接受检查的37名婴儿中，34名参加了24个月的随访检查。通过超声评估胸腺指数（一种体积估计值），并与临床变量、母乳喂养状况和疾病进行比较。纵向预测模型基于两年的数据。
24个月时，胸腺指数与临床变量、母乳喂养状况或疾病之间无显著关系。对0至24个月婴儿在4个月时母乳喂养状况的总体影响测试具有显著性，0至8个月婴儿的实际身长也是如此。估计了预测模型。
基于一项为期24个月的纵向超声研究，提出了预测模型，据此可以在出生至24个月的任何时候预测作为指标的胸腺大小。
