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
backgroundThe expanding use of bioprosthetic aortic valve replacements has raised concerns regarding the long-term durability of bioprosthetic valve prostheses. While lipoprotein(a) [Lp(a)] is implicated in the pathogenesis of native aortic valve stenosis, its impact on bioprosthetic valve degeneration leading to reintervention remains unclear.
objectiveTo evaluate the association between Lp(a) levels and structural degeneration of aortic bioprosthetic valves in patients undergoing secondary aortic valve procedure.
methodsWe retrospectively analyzed 389 patients with available Lp(a) values who underwent replacement of a degenerated aortic bioprosthetic valves between February 2001 and September 2024. Endpoint was the interval from initial surgical aortic valve replacement (SAVR) to the second aortic valve procedure either as transvascular or surgical replacement. Patients were stratified by Lp(a) levels into low (< 105 nmol/L) and high (≥ 105 nmol/L) Lp(a) groups. Associations between Lp(a) levels and time-to-reintervention were assessed using Kaplan-Meier survival analysis.
resultsOut of an initial cohort of 909 patients, 389 met the inclusion criteria. Of these, 296 patients showed low and 93 high Lp(a) levels. Baseline characteristics were comparable between both groups. The median time from initial valve implantation to the second aortic valve intervention did not differ significantly by Lp(a) group. Kaplan-Meier analysis demonstrated no significant association between elevated Lp(a) and time-to-reintervention (hazard ratio [HR] 0.81; 95% confidence interval [CI] 0.58 - 1.13; p = 0.215).
conclusionsIn this cohort of patients undergoing secondary aortic valve procedure, elevated Lp(a) levels were not associated with earlier need for reintervention. Unlike in native aortic stenosis, our findings do not support a clinically meaningful role for Lp(a) in bioprosthetic aortic valve degeneration.
