Racial and ethnic differences in risk for hysterectomy following insertion of a levonorgestrel-releasing intrauterine device: A retrospective cohort study.
Article in Contraception, 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
objectivesEvidence regarding risk for hysterectomy following treatment for benign gynecological conditions with a levonorgestrel-releasing intrauterine device (LNG-IUD) is limited. We assess whether race and ethnicity are associated with hysterectomy risk and moderate associations between other patient characteristics and hysterectomy risk. STUDY
designFrom health care records (US South; 2014-2019), we identified a retrospective cohort of 783 patients (aged 18-44 years; non-Hispanic White n = 455; non-Hispanic Black n = 208; Hispanic n = 120) receiving LNG-IUD treatment for a benign condition, followed to hysterectomy or study end (September 18, 2019). Indices measuring preinsertion bleeding, gynecological pain, and bulk symptom severity were abstracted from 4 months' medical records preceding insertion. Associations between race and ethnicity, age, symptom severity, presence of fibroids and endometriosis, prior IUD use, parity, and insurance and hysterectomy risk were investigated with Kaplan-Meier estimates and Cox regression.
resultsSeventy-six patients (9.7%) underwent hysterectomy (median follow-up: 1.7 years). Hysterectomy rates were 7.0% within 1 year, climbing to 14.9% at 4 years post-insertion. Hysterectomy rates did not differ significantly by race and ethnicity. Age at treatment, symptom severity, fibroids, parity, and insurance status were associated with hysterectomy, but only age (hazard ratio per unit increase: 1.04 [95% CI: 1.00-1.09]), bleeding severity (1.05 [1.00-1.10]), and bulk severity (1.15 [1.00-1.32]) remained associated with adjustment. There was no evidence that race and ethnicity moderated these associations.
conclusionsWe did not find statistically significant differences in hysterectomy risk for Black, Hispanic, and White LNG-IUD patients. Patients who were older and had more severe pre-insertion uterine bleeding and bulk symptoms were more likely to undergo hysterectomy. These associations did not differ by race and ethnicity. IMPLICATIONS: Among patients being treated with LNG-IUDs for benign gynecological conditions, Black, Hispanic, and White patients did not differ significantly in hysterectomy risk, but older patients and those with more severe bleeding and bulk symptoms were more likely to undergo hysterectomies.
