Univariate analysis and multivariate logistic regression analysis were used to identify independent risk factors for poor wound healing, and a predictive nomogram was constructed.<h4>Results</h4>Univariate analysis showed that white blood cell (WBC) count, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), platelet count, hypoalbuminemia, and anemia were significantly different between the two groups (<i>P</i> < 0.05). The gene discussed is CRP; the disease is anemia (phenotype).
