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
objectiveSurgery is the mainstay of treatment for low-grade endometrial stromal sarcoma (LG-ESS). While adjuvant hormone therapy is recommended for patients with advanced/recurrent disease, no consensus regarding its use among early-stage patients exists. We aimed to identify correlates of adjuvant hormone therapy use and associations of adjuvant hormone therapy and overall survival (OS) in stage I LG-ESS patients.
methodsRetrospective cohort study of patients with stage I LG-ESS who underwent hysterectomy from 2004-2019 using data from the National Cancer Database. Categorical data were compared using χ² tests. Kaplan-Meier estimates and log-rank tests were used to compare OS according to adjuvant hormone use. Hazard ratios (HRs) and 95% confidence intervals (CIs) for associations between adjuvant hormone use and OS were estimated using Cox proportional hazards regression.
resultsOf 2,386 patients included, 20.2% were treated with adjuvant hormonal therapy. Use of hormone therapy increased over time, with rates approximately doubling from 2004 to 2019 (12.6% to 24.6%). Age, tumor size, lymphovascular space invasion and adjuvant radiation were associated with adjuvant hormone therapy use. There was no association between adjuvant hormone therapy and OS (log-rank p=0.73; HR=1.05; 95% CI=0.76-1.46) for patients with LG-ESS.
conclusionUse of adjuvant hormone therapy for stage I LG-ESS has increased over time though is not associated with OS in this cohort of patients. Additional evaluation is needed to understand the impact of adjuvant hormone therapy on recurrence rates, progression rates, and quality of life to fully understand its value.
