The effect of omega-3 Polyunsaturated Fatty Acid (PUFA) prescription preparations on the prevention of clinical cardiovascular disease: a meta-analysis of RCTs.

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
importanceEvidence from systematic reviews of the cardioprotective effect of omega-3 polyunsaturated fatty acid (PUFA) remains controversial, and interventions including PUFAs dietary supplements or prescription medications cannot accurately reflect the role of PUFA RX in cardiovascular disease (CVD) prevention.
objectiveWe conducted a meta-analysis of randomized clinical trials (RCTs) to evaluate the efficacy of PUFA prescription medication in preventing CVD.
methodsTwo reviewers conducted a literature search of Embase, MEDLINE/PubMed, and the Cochrane Library from their inception to September 2023. The inclusion criteria were RCTs evaluating long-term supplementation (≥ 1 year) with PUFA prescriptions and reporting cardiovascular outcomes. Data were extracted independently by two authors, and the certainty of evidence for each outcome was assessed using the GRADE system. Random-effects models were used to estimate the risk ratios (RRs) and 95% confidence intervals (CIs). The primary outcomes were cardiovascular events. Secondary endpoints included major adverse cardiovascular events (MACEs), cardiac death, all-cause mortality, myocardial infarction, stroke, and revascularization. Subgroup analyses were performed based on PUFA components, dosage, follow-up duration, and risk status.
resultsTwelve RCTs involving 99,830 participants were included. The mean age of participants ranged from 59.4 to 74.0 years, with a follow-up period varying from 1 to 6.2 years. Compared with placebo and statins, PUFA prescription medication was associated with a reduced risk of cardiovascular events (8 RCTs, n = 75,929, RR, 0.88 [95% CI, 0.81-0.95]; P = 0.0007; I CONCLUSIONS AND RELEVANCE: PUFA prescription medication could lower the risks of cardiovascular events, cardiac death, myocardial infarction and revascularization. This research provides insight into the efficacy of PUFA prescription medications in CVD prevention and contributes to the ongoing debate on the role of PUFA products in cardiovascular outcomes.
