Impact of Sex on In-Hospital Mortality and Discharge Disposition among Renal Failure Patients Undergoing Mechanical Thrombectomy for Acute Ischemic Stroke.

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
purposeMechanical thrombectomy (MT) has improved outcomes for acute ischemic stroke (AIS); however, patients with renal failure remain at elevated risk for adverse events. Sex-based differences in outcomes following thrombectomy have been reported in heterogeneous stroke populations, but data specific to renal failure patients are limited. Understanding whether sex influences in-hospital mortality and discharge disposition in this high-risk subgroup is clinically important. MATERIALS AND
methodsWe conducted a retrospective cohort study using the 2019-2022 National Inpatient Sample to identify renal failure patients undergoing MT for AIS. Patients were stratified by sex. Multivariable logistic regression was used to assess associations between sex and in-hospital mortality and non-routine discharge, adjusting for demographic, socioeconomic, clinical, and hospital-level covariates.
resultsThe study included 3,280 unweighted hospitalizations (1,675 males; 1,605 females). After adjustment, female sex was independently associated with higher odds of non-routine discharge (adjusted odds ratio [OR] 1.536, 95% confidence interval [CI] 1.391-1.696; P<0.001) but not with in-hospital mortality (adjusted OR 0.953, 95% CI 0.874-1.038; P=0.266). Increasing age and select comorbidities were associated with both outcomes.
conclusionFemale sex was associated with increased odds of non-routine discharge but not in-hospital mortality among renal failure patients undergoing MT. These findings support equitable application of thrombectomy across sexes while highlighting the importance of sex-aware discharge planning in this high-risk population.
