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

Background: The investigation into unsaturated fatty acids has spanned an extensive period; however, the evidence supporting their therapeutic efficacy in treating acne remains inconclusive. Previous research has predominantly focused on omega-3 and omega-6 fatty acids, with limited exploration of the roles played by monounsaturated fatty acids and specific unsaturated fatty acids such as docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). Methods: To more comprehensively assess the impacts of diverse unsaturated fatty acids and their subcomponents, we employed Mendelian randomization methodology. Our primary analytical approach was inverse variance weighting (IVW), supplemented by a series of sensitivity analyses to enhance the robustness of our findings. Given the potential for overlapping single nucleotide polymorphisms (SNPs) among the various unsaturated fatty acids under investigation, we incorporated multivariate Mendelian randomization to reduce the risk of false positives. Additionally, Bayesian weighted Mendelian randomization was utilized to confirm the consistency of our results. Results: Univariate Mendelian randomization indicated that omega-3 and DHA were inversely associated with acne risk, while the omega-6 to omega-3 ratio showed a positive correlation with acne risk. Multivariate Mendelian randomization revealed that only DHA demonstrated a positive association with acne risk, a finding supported by Bayesian weighted Mendelian randomization. Conclusion: Collectively, these results suggest that our data primarily support the protective influence of DHA against acne.
