Fig. 7From: Comparison of reader agreement, correlation with liver biopsy, and time-burden sampling strategies for liver proton density fat fraction measured using magnetic resonance imaging in patients with obesity: a secondary cross-sectional studyThe limits of agreement (LOA) of sampling strategies at the segmental and whole-liver levels for intra-reader agreement decreased with the number and size of regions-of-interest. a The LOA of sampling strategies at the segmental level. b The LOA of sampling strategies at the whole-liver level. Each dot or bar represents a particular sampling strategy. The dotted line indicates an LOA of 1.5%Back to article page
