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
Background: Increased glycemic variability (GV) is frequently observed among patients in the intensive care unit (ICU) and is related to patient prognosis. Nevertheless, the relationship between GV and the prognosis of individuals with traumatic lung injury (TLI) remains inconclusive. This study mainly aimed to explore the association between GV and the prognosis of TLI. Methods: Clinical data of TLI patients in the ICU were obtained from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database. The association between GV and the risk of in-hospital mortality (IHM) in TLI patients was examined via the Cox proportional hazards (CPH) models. The potential non-linear relationship between GV and the risk of IHM was investigated through restricted cubic spline (RCS) models. Survival differences between groups were assessed by Kaplan-Meier (KM) survival analysis. Subsequently, subgroup analyses were carried out. Results: There were 1,232 patients selected from the MIMIC-IV database. CPH analysis revealed that higher GV was notably associated with an elevated risk of IHM [hazard ratio (HR) =3.555; 95% confidence interval (CI): 1.602-7.891]. RCS analysis suggested a nearly linear relationship between GV and the risk of IHM. Additionally, KM survival analysis indicated significant differences in survival rates between different GV-based groups. Conclusions: The results suggested that higher GV was related to a heightened risk of IHM in TLI patients. Nonetheless, further large-scale prospective studies are needed to confirm the causal relationship.
