Association between preoperative dementia and hospital mortality in old old patients undergoing elective gastrointestinal surgery.

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
backgroundAlthough many reports have shown that preoperative dementia affects surgical prognosis, it is unclear whether the dementia based on Mini-Mental State Examination (MMSE) affect hospital mortality in old old patients undergoing elective gastrointestinal surgery.
aimsThis study aims to investigate whether preoperative dementia might affect the outcomes of old old patients undergoing elective gastrointestinal surgery by evaluating with the MMSE.
methodsAll patients aged ≥ 75 years who undergoing elective gastrointestinal surgery form January 2015 to December 2021 in a Chinese tertiary hospital were retrospectively analyzed. Their preoperative cognitive status was evaluated using the MMSE, and analysis was performed to compare the patients with MMSE score < 24 (dementia group) or MMSE score 24-30 (non-dementia group). Risk factors for hospital mortality were explored using multivariate logistic regression analysis.
results980 patients were rolled in the study, and 102 (10.4%) patients were in the dementia group. ICU and hospital stay were longer in the dementia group. Regarding the postoperative complications, the incidence of cerebral infarction (P = 0.014), delirium (P = 0.019), and pulmonary infection (P = 0.017) was more frequent in dementia group. Hospital mortality was 11% in the dementia group and 3% in the non-dementia group (P = 0.009). Multivariate logistic regression analysis revealed that dementia (P = 0.0135), preoperative lower albumin (P = 0.0018) and malignancy (P = 0.0212) were independent risk factors for hospital mortality.
conclusionsAmong old old patients undergoing elective gastrointestinal surgery, hospital mortality was increased significantly for patients with dementia evaluating with the MMSE.
