Obesity is associated with improved progression-free survival in Microsatellite-Instability-High endometrial cancer treated with pembrolizumab.

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
objectivesTo determine the clinical predictors of response rate, progression-free survival (PFS), and overall survival (OS) to pembrolizumab in advanced or recurrent, mismatch repair deficient (MMRd) or Microsatellite Instability-High (MSI-H) endometrial adenocarcinomas.
methodsA retrospective, single institution study was conducted among women with recurrent or advanced MMRd or MSI-H endometrial adenocarcinomas treated with single-agent pembrolizumab at our institution from 2017 to 2021. Logistic regression was used for univariable and multivariable analyses. PFS and OS were estimated using the methods of Kaplan and Meier and modeled via Cox proportional hazards regression. Log-rank test was used for intergroup comparisons based on body mass index (BMI).
resultsAmong the 44 patients included in the analysis, the median BMI was 32.9 (range 18.5-51.8). Median cycles of pembrolizumab given was 11.5 (range 2-37). Median follow-up was 33 months (range 5-61) with a response rate of 63.6% and stable disease rate of 75%. When stratified by obesity status (BMI≥30), disease control rate was 59.8% in patients with a BMI < 30 and 85.2% in patients with a BMI≥30 patients (p = 0.05). On multivariable analysis, obesity was associated with increased rate of disease control (OR 4.03, 95%CI 1.09, 28) while prior smoking was associated with decreased rate of disease control (OR 0.18, 95%CI 0.03, 0.85). PFS was significantly increased among patients with a BMI≥30 (p = 0.03) but OS was similar (p = 0.5).
conclusionIn this retrospective study, obesity is associated with increased rates of disease control and improved PFS in patients treated with pembrolizumab for recurrent or advanced MMRd/MSI-H endometrial adenocarcinomas.
