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
objectivesWe describe a bilateral coronary leaflet modification technique that involves translocation of degenerated transcatheter valve leaflets before placement of valve-in-valve, named Bilateral Iatrogenic Coronary Obstruction Risk Nullification (BICORN). KEY STEPS: Key steps include the following: 1) Electrified 0.014-in ASTATO wires were traversed through the base of the right and left coronary leaflets of preexisting CoreValve, which were then swapped with 0.035-in wires; 2) Using peripheral balloons, leaflet traversal points were appropriately dilated; 3) A 26-mm Sapien valve was then advanced over the wire through the left coronary leaflet to the ascending aorta in a deployment-ready state; and 4) Right coronary leaflet was then translocated with 18-mm True balloon followed by deployment of the Sapien valve lined up to sixth node of the CoreValve. POTENTIAL PITFALLS: Translocation of preexisting valve leaflets is an uncontrolled step and can potentially lead to distal embolization and or severe aortic valve insufficiency. TAKE-HOME MESSAGES: BICORN can be considered as an option for transcatheter aortic valve in transcatheter aortic valve replacement in patients with extreme surgical risk.
