Young Age at Hysterectomy and Elevated Hypertension Risk: A Combined Observational and Mendelian Randomization Study.
Observational study in Yonsei medical journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeThis study aimed to conduct an observational analysis of the association between hysterectomy status and the risk of developing hypertension, and to determine the causality of that relationship through a Mendelian randomization (MR) study. MATERIALS AND
methodsThe study utilized two independent cohorts: 12628 female participants from National Health and Nutrition Examination Survey (NHANES) (2007-2018) for observational analysis and genetic data from the UK Biobank/IEU Open GWAS for two-sample MR. This study included 12628 participants from the 2007-2018 NHANES and used weighted logistic regression to analyze the association between hysterectomy status and the risk of developing hypertension, followed by a subgroup analysis and restricted cubic splines (RCS) to further explore the associations. A two-sample MR study was conducted to determine the causal relationships between hysterectomy status and the risk of developing hypertension and increased systolic blood pressure (SBP) and diastolic blood pressure (DBP).
resultsAdjusted, weighted logistic regression revealed a significant association between hysterectomy status and the risk of developing hypertension [odds ratio (OR)=1.26, 95% confidence interval (CI): 1.04-1.52]. Both subgroup and RCS analyses revealed that a younger age at hysterectomy was associated with a greater risk of hypertension. MR showed a causal association between genetically predicted hysterectomy status and the risk of developing hypertension (OR=1.205, 95% CI: 1.043-1.392), increased SBP (beta=9.642, 95% CI: 2.125-17.159) and increased DBP (beta=6.695, 95% CI: 2.173-11.217).
conclusionHysterectomy is associated with an increased risk of hypertension, particularly among women who undergo the procedure at a younger age.
