研究目的: |
本研究的主要目标是筛选出能帮助诊断儿童功能性腹痛病的影响因素,并通过多种机器学习算法分别建模及验证。获得最佳预测模型,并建立列线图模型以评估诊断儿童功能性腹痛病。本研究拟为儿童功能性腹痛病的早期诊断提供预测价值,帮助治疗决策。 |

|
Objectives of Study: |
The main objective of this study is to screen out the influencing factors that can help diagnose functional abdominal pain in children and model and verify them respectively through multiple machine learning algorithms. Obtain the best predictive model and establish a nomogram model to evaluate and diagnose functional abdominal pain in children. This study aims to provide predictive value for the early diagnosis of functional abdominal pain in children and assist in treatment decisions. |
