Effect of conjugated linoleic acid on blood inflammatory markers: a systematic review and meta-analysis on randomized controlled trials.
Synthesis in European journal of clinical nutrition, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers, 2 of them syntheses that pooled 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.
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/
objectivesConjugated linoleic acid (CLA) is a polyunsaturated fatty acid with attractive biological activities. Numerous studies have been conducted on the inflammation-lowering effects of CLA in in vitro and animal models. However, the effects of CLA treatment on the inflammatory markers in humans are controversial. Therefore, the objective of this study was to perform a systematic review and meta-analysis on controlled clinical trials (RCT) assessing the effects of CLA supplementation on the circulating inflammatory markers, including C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α). SUBJECTS/
methodsThe literature search of RCTs was performed using Pubmed/Medline, Scopus, ScienceDirect, Web of science, Cochrane, and Google Scholar databases from inception to March 2017. Weighted mean differences were estimated and the pooled effect size was calculated by a random effects model.
resultsOf the 427 identified studies, eleven RCTs, including 420 subjects were included in the statistical analysis. Findings suggested that CLA supplementation increased blood levels of CRP by 0.89 mg/l (95% CI: 0.11, 1.68; P = 0.025) and TNF-α levels by 0.39 pg/ml (95% CI: 0.23, 0.55; P < 0.0001). However, blood IL-6 levels were marginally decreased by 0.32 pg/ml (95% CI: -0.71, 0.07; P = 0.11) following CLA supplementation. There was a significant heterogeneity for the impact of CLA on CRP and IL-6, but not TNF-α.
conclusionsThis meta-analysis showed that CLA supplementation may increase inflammatory markers (CRP and TNF-α). There are concerns about using CLA supplementation as an anti-obesity agent among the obese population for at least a short duration.
