Objectives: This is a protocol for a Cochrane Review (diagnostic). The objectives are as follows:. To determine the diagnostic accuracy of transient elastography with CAP for diagnosis of moderate and severe hepatic steatosis in people with suspected NAFLD when compared with liver biopsy as reference standard. To achieve this, we will compare none/mild hepatic steatosis (S0 to S1) versus moderate/severe hepatic steatosis (S2 to S3); and none/mild/moderate hepatic steatosis (S0 to S2) versus severe hepatic steatosis (S3). Secondary objectives We aim to also identify the pooled sensitivity and specificity for the most common cut-off values of CAP for diagnosis of none/mild hepatic steatosis (S0 to S1) and moderate/severe hepatic steatosis (S2 to S3); or none/mild/moderate hepatic steatosis (S0 to S2) and severe hepatic steatosis (S3) in people with suspected NAFLD, and to explore potential sources of heterogeneity influencing the diagnostic test accuracy of CAP (see: Investigations of heterogeneity).
