1 · What the graph read from it

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.

2 · The registry

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

backgroundIn recent years, the impact of lipoprotein(a) (Lp(a)) on the prognosis of coronary heart disease has been increasingly recognized. Lp(a) is an independent risk factor for cardiovascular disease, and studies have shown that homocysteine (HCY) may influence the association between Lp(a) and the risk of recurrent cardiovascular events. This study investigates the association between Lp(a) levels and recurrent cardiovascular events in patients with varying HCY concentrations.

methodsWe conducted a 36-month follow-up on 530 patients with coronary heart disease and divided them into low-Lp(a) and high-Lp(a) groups based on Lp(a) levels. The incidence rates of major adverse cardiovascular events (MACE) and acute coronary events (ACE) were compared between the two groups. The association between elevated Lp(a) and cardiovascular risk in different subgroups(based on HCY concentration) was analyzed using Kaplan-Meier curves and Cox proportional hazards models.

resultsElevated Lp(a) remained a significant risk factor for both MACE (HR = 2.07, 95% CI = 1.37-3.12, P = 0.001) and ACE (HR = 2.83, 95% CI = 1.67-4.81, P = 0.001) overall. In subgroup analyses, elevated Lp(a) in patients with moderate-to-high HCY levels constituted a high-risk cohort for MACE and ACE occurrence (HR = 1.87, 95% CI = 1.01-3.46, P = 0.046;HR = 2.85, 95% CI = 1.32-6.18, P = 0.008). Among those with low HCY levels, elevated Lp(a) showed no association with either MACE or ACE (P > 0.05).

conclusionWhen HCY is elevated, patients with increased Lp(a) experience amplified risk of recurrent cardiovascular events. This association shifts when HCY is at low levels. Future efforts should emphasize combined assessment of Lp(a) and HCY and explore targeted intervention strategies to reduce residual cardiovascular risk.
