Association of Serum Secreted Frizzled-Related Protein 5 Levels With Coronary Artery Disease.
Article in Cureus, 2025. 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
Background Coronary artery disease (CAD) is the leading cause of death and premature disability worldwide. Secreted frizzled-related protein 5 (SFRP5), a recently identified adipokine, acts as an antagonist of Wingless-type family member 5A (WNT5A) signaling. Since WNT5A triggers inflammation in endothelial cells, the anti-inflammatory properties of SFRP5 play a crucial role in counteracting this effect. Lower SFRP5 levels contribute to the chronic inflammatory conditions associated with CAD by promoting WNT5A signaling. Aim This study aimed to assess serum SFRP5 levels in CAD patients and compare them with those in non-CAD patients at a tertiary care hospital. Materials and methods The study sample included 40 angiographically confirmed CAD patients as cases and 40 non-CAD patients as controls. Serum SFRP5 levels and lipid profiles were measured and compared between the two groups. Data analysis was performed using IBM SPSS Statistics for Windows, Version 26.0 (Released 2019; IBM Corp., Armonk, NY, USA), employing descriptive statistics, normality tests, t-tests, chi-square tests, and correlation analyses. A p-value of <0.05 was considered statistically significant. Results Serum SFRP5 levels were significantly lower in CAD patients (1.25 ± 0.35) compared to controls (2.46 ± 0.96) (p < 0.01). Additionally, SFRP5 showed a significant negative correlation with triglycerides and low-density lipoprotein cholesterol (p < 0.05). Conclusions This study demonstrated that serum SFRP5 levels were significantly lower in CAD patients compared to controls. Therefore, serum SFRP5 may serve as a novel biomarker for the early prediction of CAD.
