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
Objective: The goal of this study was to assess 2 analytic strategies for comparing hospital outcomes among those with emergency general surgery (EGS) conditions, comparing a conventional risk stratification method with a less utilized, but equally informative strategy. Background: EGS is a complex set of heterogeneous, time-sensitive conditions that require expeditious treatment. Patients need a mechanism to evaluate how hospitals perform for similar populations treated within the hospital and a reliable metric that benchmarks outcomes across institutions. Methods: We performed a retrospective cohort study assessing hospital outcomes for EGS Medicare beneficiaries from July 1, 2015, to June 30, 2018. Using direct standardization with balancing weights and indirect standardization with logistic regression, we compare hospital performance on a risk-adjusted composite adverse event rate. Performance based on each standardization modality was correlated using the Spearman rank coefficient. Results: There were 536,284 patients with a median (interquartile interval) age of 74.2 (72.9, 75.6) years treated at 1866 study hospitals. Direct and indirect standardization showed agreement on 92 low- and 76 high-performing hospitals. Adverse event rates for hospital rankings were strongly correlated between the 2 methods of standardization (0.83, Conclusions: Significant variation exists in EGS outcomes. Hospital performance is inconsistent between operative and nonoperative treatment. A small number of hospitals can be distinguished based on risk-adjusted outcomes regardless of analytic technique, suggesting opportunities for optimized care standardization and quality improvement.
