Dose-response relationship between risk factors and incidence of COVID-19 in 325 hospitalized patients: A multicenter retrospective cohort study

Figure 1 Receiver operating characteristic analysis of risk factors and computed tomography stages in coronavirus disease 2019 patients. CRP: C-reactive protein; AUC: Area under the curve; LDH:Lactate dehydrogenase.

Figure 2 Adjusted hazard ratios (solid lines) and 95% confidence interval (dashed lines) for coronavirus disease 2019 mortality from restricted cubic splines in a multivariate-adjusted Cox proportional hazard model. The model was adjusted for age, gender, smoking status, history of hypertension, diabetes, cancers, cardiac disease, and chronic pulmonary disease, systolic blood pressure, fasting blood glucose, total cholesterol, triglyceride, white blood cell count, CRP, creatinine, DD, LDH, procalcitonin. CRP: C-reactive protein; LDH: Lactate dehydrogenase; DD: D-dimer.
