Figure 3 Forrest plots showing comorbidities as risk factors of Crohn’s disease. Adjusted for age, sex, diabetes, hypertension, smoking, alcohol consumption, regular exercise, body mass index, anemia, chronic kidney disease and dyslipidemia. A: Compared with the other factors analyzed in this study, anemia proved to have the largest effect on the risk of Crohn’s disease (CD); B: Patients with chronic kidney disease in the middle-aged group were more likely to be diagnosed with CD; however, in the elderly population, chronic kidney disease did not prove to have statistical meaning; C: Patients diagnosed with dyslipidemia were less likely to develop CD than the control population, among those aged between 40 and 65 years.
