One-stop colonoscopy-based management of colorectal polyps and internal hemorrhoids in older adults: A real-world cohort study

Figure 1 Flow diagram of patient selection and cohort formation. The flow diagram shows the screening, exclusion, loss to follow-up, and final inclusion of patients in the analytic cohort.

Figure 2 Prevalence of colorectal lesions according to age group. Prevalence was calculated using all patients within each age group as the denominator. Adenoma, advanced adenoma, and high-grade dysplasia are shown for elderly (≥ 65 years) and non-elderly (< 65 years) patients. HGD: High-grade dysplasia.

Figure 3 Factors associated with symptom improvement following endoscopic treatment of internal hemorrhoids. A: Odds ratios and 95% confidence intervals from univariable logistic regression analysis; B: Adjusted odds ratios and 95% confidence intervals derived from multivariable logistic regression analysis. Covariates included age, sex, body mass index, hemorrhoid grade, treatment modality, anesthesia use, and total operation duration. OR: Odds ratio; CI: Confidence interval; BMI: Body mass index; RBL: Rubber band ligation; EPFS: Endoscopic polidocanol foam sclerotherapy.
