Association of Average Glucose and Glycemic Variability With 28-Day Mortality in Patients With Cardiac Arrest: A Retrospective Study.

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
backgroundBlood glucose levels and glycemic variability are associated with poor prognosis in critically ill patients. This study aims to investigate the relationship between average glucose (AG) and glycemic variability (GV) with 28-day mortality in patients with cardiac arrest (CA).
methodsThis retrospective study extracted glucose measurements during ICU stay from all patients diagnosed with CA in the eICU Collaborative Research Database (version 2.0), the Medical Information Mart for Intensive Care III (version 1.4) and IV (version 3.1), and the Emergency Intensive Care Unit of Beijing Chaoyang Hospital. Multivariable Cox proportional hazards regression models and restricted cubic spline (RCS) analysis were used to explore the associations between AG, GV, and outcomes, with subgroup analyses performed to validate the findings.
resultsIn 6110 CA patients, RCS analysis revealed a nonlinear relationship between AG and 28-day mortality (p for nonlinear < 0.001), whereas GV exhibited a linear association (p for nonlinear = 0.058). Multivariable Cox regression analysis demonstrated that AG Q4 (AG ≥ 171.75 mg/dL), GV Q4 (GV ≥ 35.8%), and Group 4 (AG ≥ 139.7 and GV ≥ 25.8%) were associated with increased 28-day death risk (AG Q4: Hazard Ratio [95% Confidence Interval] 1.90 [1.69, 2.14], p < 0.001; GV Q4: 1.45 [1.30, 1.62], p < 0.001; Group 4: 1.80 [1.61, 2.00], p < 0.001), consistent across subgroup analyses.
conclusionsOur study showed that higher AG and GV were associated with mortality in CA patients. Furthermore, AG and GV were independent predictors of 28-day mortality in these patients.
