Safety and efficacy of docosahexaenoic acid supplementation during neoadjuvant breast cancer therapy: Findings from the phase II, double-blind, randomized controlled DHA-WIN trial.
Trial report in International journal of cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis 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
There is limited clinical evidence of docosahexaenoic acid (DHA) efficacy during breast cancer neoadjuvant chemotherapy (NAC). This randomized, double-blind, placebo-controlled trial aimed to investigate the safety and efficacy of DHA supplementation in breast cancer patients undergoing NAC. Participants (n = 49) were assigned to receive either DHA 4.4 g/day orally (algae triacylglycerol) or a placebo (corn/soy oil) over six cycles (18 weeks) of NAC. The primary outcome was the evaluation of changes in the percentage of Ki-67 expression, assessed by immunohistochemistry analysis from pre- to post-treatment. Secondary outcomes included pathological complete response, incidence of adverse effects, and 3-year survival analysis. Compliance was evaluated by fatty acid analysis of plasma phospholipids and erythrocyte total lipids quantified by gas-liquid chromatography. The expression of Ki-67 significantly decreased in both groups, with no significant effects of the DHA intervention (p = 0.38). When stratified by breast cancer subtype, there was a trend of greater reduction in Ki-67 expression in the human epidermal growth receptor 2 (HER2+++) subtype in the DHA group compared to placebo (p = 0.1). The % of DHA in erythrocytes and plasma phospholipids was increased by two-fold at 9 and 15 weeks of therapy in the DHA group, while it remained unchanged in the placebo group (p-interaction <0.001). There was no reported incidence of adverse effects related to the intervention, and no significant effects were found in the other secondary outcomes. NAC significantly decreased the expression of Ki-67, with no additional beneficial effects observed by DHA supplementation. Further research is necessary to confirm these findings.
