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
The cause and effect between serum micronutrients and erectile dysfunction (ED) is not clear. The purpose of this study was to evaluate the causal relationship between micronutrients and ED by Mendelian randomization (MR) analysis. We used the published genome-wide association study (GWAS) data for two-sample MR analysis. This study utilized inverse variance weighted (IVW), MR egger, weighted median, simple mode, and weighted mode method to assess the causal relationship between serum micronutrients and ED. IVW is considered the standard method for MR analysis. We used Cochran's Q tests to evaluate the heterogeneity. To investigate horizontal pleiotropy, this study employed the MR Egger method. Additionally, leave-one-out analysis was used to evaluate the influence of individual genetic loci on the results. The results showed that there was a causal relationship between serum copper and ED, and it was positively correlated with ED (OR = 1.115, CI = 1.00-1.24, p = 0.014). There was no significant correlation between other micronutrients and ED. Sensitivity analysis results indicated that our findings exhibit no heterogeneity or pleiotropy, thereby strengthening our conclusions. Serum copper is a risk factor for ED, which provides a new idea for the diagnosis and treatment of ED in the future. However, further experiments are needed to elucidate the underlying mechanisms.
