Nonlinear models of injury risk and implications in intervention targeting for thoracic injury mitigation

Objective: Field data analyses often use either parametric or nonparametric means to describe the relationship between risk and various predictor variables. This study sought to evaluate a hybrid approach using semiconstrained multivariate nonlinear spline-based analysis.Methods: Data were compiled from NASS-CDS years 1998–2015, selecting belted occupants age 16+ in collisions with a principal direction of force (PDOF) from 10 o’clock to 2...
