Sex-difference in the association between Triglyceride-Glucose (TyG) index and dementia.

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
Purpose: This study aims to evaluate the association between the insulin resistance as assessed by Triglyceride-Glucose (TyG) index and dementia and to determine whether this relationship varies by sex. Methods: We assessed TyG index in older patients admitted to an Italian Memory Clinic with different cognitive status: 335 (71% females-F) participants with Alzheimer's disease (AD), 99 (61% F) with vascular dementia (VAD), 301 (67% F) with mixed dementia (MIXED: AD + VAD), 442 (57% F) with mild cognitive impairment (MCI), and 173 cognitively healthy controls (61% F). Results: We found that only in females high TyG index was associated with a greater probability of receiving a diagnosis of MCI (odd ratio - O.R.: 1.91, 95% confidence interval - C.I.: 1.08-3.34), VAD (O.R.: 2.23; 95% C.I.: 1.10-4.51), and MIXED (O.R.: 1.92, 95% C.I.: 1.10-3.33), but not AD (O.R.: 1.07, 95% C.I.: 0.63-1.85). Notably, these associations remained significant in a multi-adjusted model, including age, smoking, total cholesterol and comorbidities. Conclusions: Our findings suggest that insulin resistance may be a risk factor for dementia with a cerebrovascular component, but only in older females.
