NCT05686785

Brief Summary

The aim of this study is to assess agreement, smallest detectable change, and reliability of repeated measurements of liver stiffness of transient elastography in patients with chronic viral hepatitis, and to explore factors associated with disagreement.

Outcome Measures

Primary Outcomes (1)

  • Disagreement defined as a difference in TE results between operators in KPa of ≥ 33%, as well as the smallest detectable change, SDC95.

    Disagreement, expressed as 1) the proportion of participants with inter-rater differences at or above our prespecified threshold (33%) and 2) the smallest detectable change, representing the difference needed to state with 95% certainty that a change had occurred in the underlying fibrosis (SDC95).

    Assessed at a 30 min visit to the outpatient clinic

Secondary Outcomes (2)

  • Reliability, estimated using the intra-class correlation

    Assessed at a 30 min visit to the outpatient clinic

  • Patient and exam characteristics associated with inter-rater differences above our prespecefied threshold.

    Assessed at a 30 min visit to the outpatient clinic
