Scatter plot and comparison of the 18 F-FDG-PET/CT results between NWL and NWO subjects. A scatter plot of the 18 F-FDG-PET/CT results was drawn, and a comparison between the NWL and NWO subjects was performed. (A) Carotid mean SUV, (B) carotid maximum SUV, (C) carotid mean TBR, and (D) carotid maximum TBR. 18 F-FDG-PET/CT, 18 F-fludeoxyglucose positron emission tomography/computed tomography; SUV, standardized uptake value; TBR, target-to-background ratio; NWL, normal weight lean; NWO, normal weight obesity. Horizontal lines in the graph indicate means, whereas perpendicular lines denote the standard deviation. *p < 0.05 versus NWL. #p < 0.001 versus NWL.
