Vitamin D and risk of thyroid cancer: a two-sample Mendelian randomization study.
Article in Discover oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveTo investigate the causal effect of serum 25-hydroxyvitamin D (25(OH)D) on the risk of thyroid cancer (TC) by a two-sample Mendelian randomization (MR) analysis.
methodsWe analyzed data from two genome-wide association studies (GWAS), including 25(OH)D concentration levels in 417,580 individuals and 1415 individuals for TC. Genetic variants associated with serum 25(OH)D were selected as instrumental variables (IVs). The inverse-variance weighted (IVW) method served as the primary approach of MR analysis was used to evaluate the sensitivity of 25(OH)D to TC risk, while the weighted-median method, MR-Egger method, weighted mode and simple mode were employed as supplementary analyses. Cochran's Q test was used to test IV heterogeneity, MR-Egger regression test and MR-PRESSO global test were used to determine IV pleiotropy, and Leave-one-out analysis was used to check the stability of the results.
results112 SNPs associated with serum 25(OH)D were identified as IVs. The IVW method showed a causal relationship between 25(OH)D and TC risk (OR = 0.761, 95% CI 0.584-0.991, P = 0.043). The results of the weighted-median method (OR = 0.858, 95%CI 0.606-1.216, P = 0.389), MR-Egger method (OR = 0.782, 95% CI 0.552-1.108, P = 0.169), weighted mode (OR = 0.779, 95%CI 0.568-1.068, P = 0.123) and simple mode (OR = 0.616, 95% CI 0.218-1.739, P = 0.362) enhance the credibility of the IVW results. Cochran's Q test, MR-Egger regression test and MR-PRESSO global test suggest that there is no significant heterogeneity and pleiotropy in IV. The leave-one-out analysis indicates that the results are stable.
conclusionThere is a causal relationship between circulating vitamin D concentration and TC risk in the population. The lower the vitamin D levels, the higher the TC risk.
