Effect of Fibrates on Lipoprotein-associated Phospholipase A2 Mass and Activity: A Systematic Review and Meta-analysis of Controlled Clinical Trials.
Synthesis in Current pharmaceutical design, 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
backgroundIn vascular tissue, macrophages and inflammatory cells produce the enzyme lipoprotein- associated phospholipase A2 (Lp-PLA2). Treatment with fibrates decreases Lp-PLA2 levels in individuals with obesity and metabolic syndrome; however, these findings have not been fully clarified.
objectiveThe goal of this study was to investigate the possible effects of fibrate therapy on Lp-PLA2 mass and activity through a meta-analysis of clinical trials.
methodsWeb of Science, PubMed, Scopus, Google Scholar, and ClinicalTrials.gov databases were searched using MeSH terms and keywords. Randomized controlled trials (RCT) evaluating the effect of statins on Lp- PLA2 mass and/or activity were included in the meta-analysis. Quantitative data were analyzed using a random- effects model and the generic inverse variance method.
resultsThe meta-analysis of 10 clinical trials indicated that fibrate treatment has no significant effect on Lp- PLA2 mass (fibrate vs. placebo/nothing = WMD: -3.29 ng/ml, 95% CI: -21.35, 14.78, p = 0.72; fibrate vs. active control = WMD: -1.08 ng/ml, 95% CI: -51.38, 49.22, p = 0.97); Lp-PLA2 activity (fibrate vs. active control = WMD: 0.84 nmol/ml/min, 95% CI: -0.17, 1.84, p = 0.10); HDL-LpPLA2 activity (fibrate vs. active control = WMD: 0.77 nmol/ml/min, 95% CI: -0.33, 1.88, p = 0.17); and secretory PLA2 (fibrate vs. active control = WMD: 0.37 ng/ml, 95% CI: -1.22, 1.97, p = 0.65). Also, the results of the sensitivity analysis were robust for all these parameters.
conclusionIn conclusion, fibrate therapy did not reduce the mass and activity of Lp-PLA2.
