1 · What the graph read from 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.

2 · The registry

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

backgroundBased on current knowledge, omega-3 fatty acids help to reduce the concentration of C-reactive protein (CRP). However, the dose-response effect and the strength of this effect are not entirely clear.

methodsWe systematically searched and screened databases to include eligible studies. This study incorporates a random effect, as well as dose-response meta-analyses using a restricted cubic spline model.

resultsForty randomized clinical trials were analyzed. Results demonstrated significant non-linear dose-response efficacy in the reduction of CRP concentration in patients with cardiovascular disease, metabolic syndrome, and hypertension up to 1200 mg/day of EPA and DHA. In addition, there was a linear decrease in CRP concentration in the dyslipidemia population. The meta-analysis results did not show any significant reduction of CRP in overweight and obese participants, and the dose-response analysis failed to show any apparent reduction. In type 2 diabetes, pooling the results revealed a significant reduction in CRP; however, the combination of EPA and DHA failed to show significant dose-response efficacy in changing CRP concentration.

conclusion1200 mg/day of EPA and DHA may help to reduce CRP concentration in patients with cardiometabolic disorders. This reduction is clinically significant, and thus intervention with omega-3 fatty acids should be considered for this population.
