Fig. 4From: Determining rib fracture age from CT scans with a radiomics-based combined model: a multicenter retrospective studyOnline dynamic nomograms for classifying rib fracture age between < 3 and ≥ 3 weeks (a) and between 3–12 weeks and > 12 weeks (b). The figure displays the probabilities (with a 95% confidence interval) determined by the combined model for rib fracture ages of ≥ 3 weeks and > 12 weeks.
