For each pair of compared tests, the individual test comparisons p values (after adjustment for alpha risk) are indicated, along with the AUROC of each respective test.

AUROC, area under the receiver operating characteristic curve; CAP controlled attenuation parameter; FLI, fatty liver index; HSI, Hepatic steatosis index; MRI-PDFF magnetic resonance proton density fat fraction; ST, SteatoTest.
