Registered outcomes3
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Pain Assessment Using Visual Analogue Scale | Five minutes after sheath removal | the patients' feeling of pain in the forearm, and it was measured using a visual analogue scale (VAS), applied at the end of the procedure by an interventional nurse. The VAS consists of a single line measuring 100 mm, anchored by verbal descriptors, saying 'no pain' and 'worst possible pain'. Higher values mean a worse pain. |
| Secondary | Procedure Duration | Immediate | Procedure duration, from artery catheterization up to removal of sheath. |
| Secondary | Radiation Exposure | Immediate | Total radiation required to complete the procedure. |
