Combined glycated hemoglobin index and red cell distribution width predict in-hospital mortality in critically ill sepsis patients based on MIMIC-IV analysis.

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
Red cell distribution width (RDW) and glycated hemoglobin index (HGI) is considered an important tool for assessing the prognosis of sepsis patients, closely related to the risk of mortality associated with sepsis. This study investigates the association between the HGI combined with RDW and the risk of in-hospital mortality in patients with sepsis. We analyzed data from 13,726 sepsis patients who were admitted to the intensive care unit (ICU) for more than 24 h, sourced from the American Medical Information Mart for Intensive Care (MIMIC-IV) database. Kaplan-Meier survival curves and multivariable Cox regression analyses were employed to assess the impact of various variables on patient outcomes, stratified by quartiles of HGI and RDW. Additionally, restricted cubic spline (RCS) analysis was utilized to explore how changes in HGI and RDW might influence the studied outcomes. The results indicated that the highest quartile (Q4) of the combined metrics significantly increased in-hospital mortality compared to the lowest quartile (Q1) (p < 0.0001). Multivariable Cox regression analysis revealed that patients in Q4 faced the highest risk of in-hospital mortality (hazard ratio: 1.22, 95% confidence interval: [1.10-1.36], p < 0.001). RCS analysis demonstrated a nonlinear relationship between HGI-RDW and the risk of adverse outcomes. Further analysis identified significantly elevated risks in patients over 65 years old, those who were widowed, those receiving macrolide antibiotics, and those with congestive heart failure or severe liver disease. In conclusion, elevated levels of the combined HGI and RDW metrics are independent risk factors for adverse outcomes in critically ill patients with sepsis, associated with increased mortality.
