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
objectiveCytoreductive surgery serves as a cornerstone intervention for advanced epithelial ovarian cancer (EOC), yet some patients decline the procedure despite clinical recommendations. This study aimed to evaluate survival outcomes and identify sociodemographic and clinical factors associated with this decision in advanced EOC patients.
methodsA retrospective analysis of EOC cases from the Surveillance, Epidemiology, and End Results (SEER) database (2004-2021) was conducted, including patients with stage III/IV EOC recommended for surgery. Patients were categorized into surgical and non-surgical cohorts. Propensity Score Matching (PSM) was applied to adjust for baseline differences, and survival outcomes were compared using Kaplan-Meier and Cox proportional hazards models. Logistic regression analysis was performed to identify predictors of surgery declination.
resultsOf the 21,988 patients included, 363 (1.7%) were in the non-surgery group. Following a median follow-up of 33 months, patients in the non-surgical cohort demonstrated significantly lower overall survival (OS) compared to the surgical cohort, with mean OS of 17.8 months versus 45.8 months, respectively (P < 0.001). The Cox model showed increased mortality risk for the non-surgical group post-PSM (HR, 1.87; 95% CI, 1.62-2.15). Non-Hispanic Black, older age, lower household income, nonmetropolitan residence, and unmarried status were associated with higher odds of surgery refusal.
conclusionDeclining surgery is associated with significantly poorer survival in advanced EOC. Sociodemographic factors play a key role in surgical decision-making, underscoring the need for targeted interventions to improve access to surgical care and reduce disparities in EOC treatment outcomes. Further studies should explore the impact of specific chemotherapy and comorbidities on surgery refusal and survival.
