Effects of Fish Oil Supplementation on Serum C-Reactive Protein Levels in Trained Individuals: A Systematic Review of Clinical Trials.
Review in Clinical nutrition research, 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
Exercise, especially when prolonged or highly intense, can temporarily increase inflammation in both trained and untrained individuals. C-reactive protein (CRP) is an established biomarker of inflammation. However, clinical trials assessing the impact of fish oil supplementation on CRP levels in trained individuals have yielded inconsistent and often contradictory results. The main objective of this study was to conduct a systematic review of clinical trials exploring the effects of fish oil supplementation on CRP levels among trained individuals. We performed structured searches on the PubMed, Scopus, and ISI Web of Science databases for articles published from the earliest available date until September 2023. Of the 385 articles found and screened, three clinical trials met our criteria for inclusion in this review. The results suggested that fish oil supplementation may help prevent spikes in CRP levels after exercise. However, only one of the three studies produced statistically significant findings. The differences in statistical significance among these studies could be due to variations in the study design, sample populations, dosages, and duration of supplementation. In summary, this systematic review provides evidence that fish oil supplementation can reduce circulating CRP levels in trained individuals. Additional studies with long-term follow-up and larger sample sizes are needed to investigate this effect further.
