Development and multiple visualization methods for the therapeutic effects prediction model of five-flavor Sophora Flavescens enteric-coated capsules in the treatment of active ulcerative colitis: A study on model development and result visualization
Introduction
The aim of this study was to develop a Therapeutic Effects Prediction Model (TEPM) for the treatment of active ulcerative colitis (UC) using Five-flavor Sophora Flavescens Enteric-coated Capsules (FSEC). This study also aimed to systematically review various visualization methods for the TEPM results and present the model results of FSEC as an example.
Methods
274 patients were randomly assigned to the training and testing datasets in a 7:3 ratio. We employed Least Absolute Shrinkage and Selection Operator (LASSO) regression to select predictive factors and constructed TEPM using logistic regression to assess the probability of disease remission. We assessed model performance by the area under the curve (AUC) and calibration curve. We utilized interactive nomograms, online calculators, scoring systems, graphical scoring tables, as well as the SHapley Additive exPlanations (SHAP) and Local Interpretable Model-agnostic Explanations (LIME) methods to present the model results.
Results
LASSO regression selected several predictors, including erythrocyte sedimentation rate, age, disease type, microscopic bleeding, pus, bridge, disease location, and pain. The AUC of the testing datasets was 0.699, and the calibration curve showed poor performance. The interactive nomogram, online calculator, and the SHAP method were suitable for datasets with predominantly continuous predictors, while scoring systems, graphical scoring tables, and the LIME method might be more appropriate for datasets with fewer continuous predictors. Physicians, researchers, and policymakers could benefit from detailed visualizations using interactive nomogram, the SHAP method, and the LIME method. Scoring systems, graphical scoring tables, and online calculator were available to the general public and non-experts. Scoring systems, graphical scoring tables, and online calculator could provide an overview of the model prediction results, while interactive nomogram, the SHAP method, and the LIME method were recommended for illustrating the complexity and rationality of the model prediction results.
Conclusion
Our study demonstrated that TEPM could predict the potential of FSEC to induce disease remission in patients with active UC. However, the poor calibration curve might be due to the limited sample size. Larger-scale multicenter studies will be needed in the future. Selecting an appropriate visualization method for TEPM should be based on the datasets, audience, and research objectives.
期刊介绍:
The European Journal of Integrative Medicine (EuJIM) considers manuscripts from a wide range of complementary and integrative health care disciplines, with a particular focus on whole systems approaches, public health, self management and traditional medical systems. The journal strives to connect conventional medicine and evidence based complementary medicine. We encourage submissions reporting research with relevance for integrative clinical practice and interprofessional education.
EuJIM aims to be of interest to both conventional and integrative audiences, including healthcare practitioners, researchers, health care organisations, educationalists, and all those who seek objective and critical information on integrative medicine. To achieve this aim EuJIM provides an innovative international and interdisciplinary platform linking researchers and clinicians.
The journal focuses primarily on original research articles including systematic reviews, randomized controlled trials, other clinical studies, qualitative, observational and epidemiological studies. In addition we welcome short reviews, opinion articles and contributions relating to health services and policy, health economics and psychology.
