Advanced Haemodynamic Monitoring During Transfemoral Aortic Valve Replacement: A Prospective Pilot Study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This pilot study aims to compare advanced and standard haemodynamic monitoring during TAVI in terms of predicting and avoiding hypotension. Intraoperative hypotension influences postoperative outcomes by increasing mortality, renal failure, and cardiac complications. In TAVI (transaortic valve implantation), haemodynamic stability is essential because the patients are usually old and vulnerable. Fifty patients underwent transfemoral TAVI under standard anaesthetic care. Blood pressure was measured invasively, using Edwards Acumen sensors connected to a HemoSphere monitor. The signal was simultaneously fed to anaesthesia monitors. Patients were randomly divided into two groups: in the test group, the Edwards monitor with the HPI (hypotension prediction index) values was available to the anaesthetist, whereas in the control group, the HemoSphere monitor was covered. The primary endpoint of the study was the time-weighted average of intraoperative hypotension, which is calculated from the intensity and duration of hypotension, adjusted for the duration of surgery (TWA
