1 · What the graph read from it

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.

2 · The registry

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

backgroundDelirium is a common neuropsychiatric complication following major gastrointestinal surgery and is associated with poor postoperative outcomes. Patients undergoing gastric surgery often experience significant metabolic stress and insulin resistance, which may contribute to delirium. The triglyceride-glucose (TyG) index is a simple surrogate marker of insulin resistance, but its predictive value for postoperative delirium in gastric surgery patients remains unclear.

methodsThis retrospective study used data from the MIMIC-IV database and included 819 ICU patients after gastric surgery. Exposure was the triglyceride-glucose (TyG) index from first available labs; outcome was ICU delirium assessed by CAM-ICU. Associations were examined with multivariable logistic regression, with standard covariate adjustment.

resultsIncreased ICU delirium was independently linked to a higher TyG index (OR = 1.25, 95% CI: 1.01-1.56). RCS revealed a U-shaped relationship. The association remained stable after PSM and across multiple subgroups. SHAP analysis confirmed TyG as a meaningful predictor.

conclusionA greater TyG index was linked in this retrospective analysis to a higher incidence of postoperative delirium in individuals after gastric surgery. These findings support preoperative risk stratification and targeted monitoring to enhance peri-operative safety and recovery in gastric surgery patients, and prospective studies are warranted to validate its clinical utility.
