The original data on thyroid lesions used in the study were extracted from the registries of the Departments of Pathology of District Hospitals in Guelma and El-Taref (Eastern Algeria), as well as from clinical records from a tertiary referral treatment center in the nearby city of Constantine. Data on cancer incidence from two population-based cancer registries in Algiers and Sétif were used for comparison.
