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.

Outcome:

Predict the risk of functional abdominal pain in children through machine learning models

Type:

Primary indicator

测量时间点:

就诊后通过统计分析软件完成

测量方法:

收集儿童功能性腹痛病调查问卷,采用Fisher精确性检验对分类变量进行组间比较;采用t检验或Wilcoxon秩和检验对连续性变量进行组间比较。使用LASSO回归方法筛选有意义的变量,采用logistic回归、随机森林、决策树和支持向量机模型分别进行建模和验证。

Measure time point of outcome:

It is completed through statistical analysis software after the visit

Measure method:

Questionnaires on functional abdominal pain in children were collected, and Fisher's accuracy test was used to compare the categorical variables between groups. The t-test or Wilcoxon rank sum test was used to compare the continuous variables between groups. Meaningful variables were screened using the LASSO regression method, and logistic regression, random forest, decision tree and support vector machine models were respectively used for modeling and verification.
