Registered outcomes7
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Within-session repeatability coefficient of EUS-PPG measured by the same expert operator | During the index EUS-PPG procedure | The repeatability coefficient will be calculated as 2.77 multiplied by the within-subject standard deviation of paired EUS-PPG measurements in the same-expert group. It will be reported in mmHg and as a percentage of the cohort mean, with a 95% confidence interval. |
| Secondary | Inter-operator reproducibility coefficient of EUS-PPG | During the index EUS-PPG procedure | The reproducibility coefficient will be estimated from paired EUS-PPG differences when different operators perform the two measurement sets and will be reported in mmHg and as a percentage, with a 95% confidence interval. |
| Secondary | Variance components of repeated EUS-PPG measurements | During the index EUS-PPG procedure | A mixed-effects model using all individual readings will estimate patient-, procedure-list-, operator-, measurement-set-, and reading-level variance components. |
| Secondary | Intraclass correlation coefficient for paired EUS-PPG measurements | During the index EUS-PPG procedure | Two-way absolute-agreement intraclass correlation coefficients will be reported overall and by operator configuration with 95% confidence intervals. |
| Secondary | Bland-Altman agreement of paired EUS-PPG measurements | During the index EUS-PPG procedure | Bias and 95% limits of agreement will be calculated overall and separately by operator pairing. |
| Secondary | Discordant classification at portal pressure gradient thresholds of 10 mmHg and 12 mmHg | During the index EUS-PPG procedure | The proportion of participants whose classification crosses the 10-mmHg or 12-mmHg threshold between the two measurement sets will be reported. |
| Secondary | Procedure-associated adverse events | From the index procedure through 30 days | Adverse events will include bleeding, pain, hemoglobin decrease, sedation-related events, unplanned admission or prolongation of stay, transfusion, and unplanned intervention. |
