We performed a case–control, retrospective, single-center study including all consecutive patients undergoing SBCE in the Gastroenterology Department of a university-affiliated Hospital, between January 2014 and August 2020. All patients with PGTT in SBCE in the given study period were consecutively included (cases). Patients without PGTT were randomized (controls), using an automatic number randomization software (Winpepi), to attain a 1:2 cases to controls ratio.Small-bowel capsule endoscopy was performed for various indications such as overt gastrointestinal (GI) bleeding, occult GI bleeding (anemia and/or positive fecal occult blood test), and suspected and established Crohn’s disease. We excluded patients under 18 years and with previous gastric surgery.Demographic and clinical data were collected by reviewing medical records and included patients’ age, gender, smoking habits, comorbidities (including diabetes, arterial hypertension, chronic kidney disease, cirrhosis, heart failure, cerebrovascular disease, hypothyroidism, depression, obesity (BMI ≥ 30 kg/m
