Baseline characteristics of the study subjects were recorded. Risk factors related to GBP formation were analyzed. All participants' series of abdominal sonography examinations in our hospital were also retrospectively reviewed to reveal the presence of GBPs through second-look sonography.Among 1311 participants, 946 participants (72.2%) had clinically evident FLD, as documented using abdominal sonography; GBPs were found in 233 (24.6%) subjects with FLD. The incidence of FLD was significantly associated with the presence of GBP (P < .001; OR: 4.16, 95%
