Efficacy of flaxseed oil compared with fish oil supplementation in the treatment of coronary heart disease: a retrospective study.
Article in Journal of thoracic disease, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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: Many studies have demonstrated the beneficial effects of omega-3 fatty acids in animal models and human diseases. Compared with commonly used fish oil, flaxseed oil has better palatability. However, the relative efficacy of the two types of oil on the cardiovascular health of type 2 diabetes mellitus (T2DM) patients with coronary heart disease (CHD) is unclear. Methods: This was a retrospective study based on the prospectively maintained database of Hubei Provincial Hospital of Traditional Chinese Medicine. Patients meeting the inclusion criteria were enrolled and then divided into two groups: the flaxseed oil group received 1,000 mg flaxseed oil, which contains 400 mg of α-Linolenic acid, as their omega-3 fatty acid source; the fish oil group received 1,000 mg of fish oil, which contains 250 mg of eicosapentaenoic acid and 150 mg of docosahexaenoic acid. The primary outcome was cardiovascular risk biomarker changes between the two groups. P values less than 0.05 were considered statistically significant. Results: A total of 120 patients were enrolled in the present study: 60 in the flaxseed oil group and 60 in the fish oil group. After a median follow-up of 10.0 weeks (95% CI: 8.4-11.6 weeks), flaxseed oil was found to be significantly better at reducing serum insulin levels and high-sensitivity C-reactive protein (hs-CRP) levels than fish oil (P=0.03 and P=0.02, respectively). The effects of flaxseed oil and fish oil on homeostatic model assessment for insulin resistance (HOMA-IR), fasting plasma glucose (FPG); body weight, and body mass index (BMI) were found to be similar. Moreover, patients who received flaxseed oil tended to have a better overall survival than those who received fish oil, although the difference was not statistically significant (P=0.067). Conclusions: Compared with fish oil, flaxseed oil was more effective in reducing serum insulin levels and hs-CRP levels for T2DM patients with CHD. For these patients, flaxseed oil might become a novel choice.
