Prognostic value of lipoprotein(a) in a primary prevention ambulatory cohort.
Article in Clinical research in cardiology : official journal of the German Cardiac Society, 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
aimsLipoprotein(a) [Lp(a)] is a novel biomarker for Atherosclerotic cardiovascular disease prediction. Yet, given the scarcity in high-quality evidence, its use in routine primary prevention screening is lacking. For this reason, we aimed to assess Lp(a) prognostic utility during routine screening.
methodsA retrospective cohort of adults with available Lp(a) measurement, taken during a screening program (2008-2024) in a tertiary care center. Major adverse cardiovascular events (MACE) was the study primary outcome. The optimal Lp(a) threshold was evaluated using spline curve analysis and validated by Cox regression models adjusted for clinical and laboratory covariates. Subgroup analyses were performed in patients with SCORE2 and PCE data.
results3052 people were included with a median (IQR) follow-up of 6.4 (3.5-12) years. Lp(a) threshold of 50 mg/dL was identified as a risk inflection point. High Lp(a) (> 50 mg/dL) was associated with increased MACE risk, independent of clinical data (HR 1.55, 95% CI 1.10-2.17, p = 0.011) or different laboratory variables (HR 1.62, 95% CI 1.07-2.46). High Lp(a) remained a predictor for MACE in models incorporating the SCORE2 and PCE scores, and its incorporation into these scores improved their performance in high-risk patients. In people with cardiovascular comorbidities, the optimal Lp(a) threshold for MACE prediction was 61 mg/dL, while it was 48.4 mg/dL in those without (n = 2778).
conclusionsIn a large ambulatory and mostly healthy cohort, Lp(a) showed a strong predictive utility for cardiovascular events. These findings support the integration of Lp(a) into primary cardiovascular risk assessment and role in guiding emerging targeted therapies.
