Demographic and clinical characteristics of patients with and without gastric antral vascular ectasia (GAVE) during preliminary screening. Preliminary screening data were abstracted from patient charts. These data are not included in the SCOT clinical database and hence have not been subject to data management checks or onsite reviews by clinical monitors.
