Mid-term valve performance and durability of the Ozaki procedure in patients on chronic dialysis.
Article in JTCVS open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: To compare the hemodynamic performance and durability of the Ozaki procedure in patients with end-stage renal disease on chronic dialysis between patients not on dialysis and patients on dialysis undergoing bioprosthetic aortic valve replacement (bAVR). Methods: Between January 1, 2007, and May 1, 2021, 155 adults on dialysis underwent the Ozaki procedure at Toho University Ohashi Medical Center. Mean aortic valve gradient, aortic regurgitation grade, and freedom from reoperation were compared between 121 propensity score-matched patients not on dialysis undergoing the Ozaki procedure and 125 age-matched patients on dialysis undergoing valve replacement with a stented bovine pericardial bioprosthesis at Cleveland Clinic between January 1, 2001, and January 1, 2022. Results: Five years after the Ozaki procedure, matched patients on dialysis were less likely to have moderate/severe regurgitation (1.7%) compared to those not on dialysis (4.1%). In the 2 groups, mean aortic gradient was 7 mmHg and 9 mm Hg, respectively ( Conclusions: In patients on chronic dialysis undergoing the Ozaki procedure, hemodynamics and durability are similar compared with those not on dialysis, and mean gradients are lower compared with those receiving a bioprosthesis. These findings support use of the Ozaki procedure in patients on dialysis requiring aortic valve replacement.
