This study developed a clinical model to identify allergic rhinitis (AR) candidates for pre-exposure prophylaxis (PrEP). The model uses routine medical data for early screening, improving resource allocation and health management.
Area of Science:
- Allergy and Immunology
- Clinical Prediction Modeling
- Public Health
Background:
- Limited risk-forecasting models exist for allergic rhinitis (AR).
- Effective models are needed to guide AR pre-exposure prophylaxis (PrEP) in clinical practice.
- Routine medical questionnaires can potentially be used for AR risk assessment.
Purpose of the Study:
- To develop and validate a clinical model for identifying AR PrEP candidates.
- To utilize routine medical questionnaire data for AR risk prediction.
- To aid in the effective deployment of resources for AR management.
Main Methods:
- A cohort of 877 participants across 10 Chinese provinces was studied (2019-2021).
- Clinical characteristics and allergen exposure history were collected via interviews.
- Least Absolute Shrinkage and Selection Operator (LASSO) and logistic regression models were employed for risk factor identification and model construction.
Main Results:
- Two nomograms were developed to identify AR based on sensitization patterns.
- Models demonstrated an approximate area under the curve (AUC) of 0.7 for predictive power.
- Calibration curves showed good agreement, indicating model reliability.
Conclusions:
- The developed models show good performance in predicting AR.
- These models can serve as potential automatic screening tools for AR PrEP candidates.
- Early identification of AR candidates can optimize resource allocation and health management.
