According to univariate analysis, statistically significant indicators (p < 0.05) were included in multivariate logistic regression analysis, including age ≥ 60 (p < 0.01), age ≥ 70 (p < 0.01), age ≥ 80 (p < 0.01), weight (p = 0.02), high BMI (p = 0.01), fracture (p < 0.001), spinal disease (p < 0.001), OA (p = 0.04), fragility fracture (p < 0.001), hip fracture (p < 0.001), pelvic fracture (p < 0.01), iron supplements (p = 0.03), hypoalbuminaemia (p < 0.001), anaemia (p < 0.001), and CRP (p < 0.01). Here, CRP is linked to bone fracture.
