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

backgroundThe C-reactive protein-triglyceride-glucose index (CTI) has emerged as an innovative composite marker for evaluating metabolic-inflammatory dysregulation, integrating markers of insulin resistance and systemic inflammation. However, the association between CTI and cardiovascular disease (CVD) or its mortality has rarely been studied. This study sought to examine CTI's associations with CVD mortality, CVD incidence, and all-cause mortality.

methodsThis study included 8,679 adults from the National Health and Nutrition Examination Survey (NHANES) 2001-2010, 2015-2018. The CTI was derived as: 0.412* Ln (CRP [mg/L]) + Ln (TG [mg/dl] × FPG [mg/dl])/2, with participants categorized into quartiles. We employed Kaplan-Meier curves, cox proportional hazards model, logistic regression analyses, and restricted cubic spline (RCS) to evaluate CTI's associations with CVD mortality, total CVD incidence, and all-cause mortality across sex-stratified, age-specific, and glycemic subgroups.

resultsIn this study, CTI was significantly and positively associated with CVD mortality, total CVD incidence, and all-cause mortality. CTI significantly predicted both CVD mortality (HR 2.28 [1.69-3.24]) and all-cause mortality (HR 2.14 [1.76-2.55]). Additionally, the CTI index correlated with the risk of total CVD (OR 2.85, 95% CI 2.32-3.52), congestive heart failure (OR 3.66, 95% CI 2.46-5.35), coronary heart disease (OR 2.82, 95% CI 1.95-3.97), angina pectoris (OR 2.85, 95% CI 1.89-4.22), heart attack (OR 2.59, 95% CI 1.89-3.52), and stroke (OR 2.86, 95% CI 2.00-3.85). Specifically, the association was similar between male and female, and similar in young participants and elderly participants. In different glycemic status, high levels of CTI were found to be linked to an increased risk of CVD in individuals without diabetes mellitus (DM). However, this association was not observed in individuals with DM.

conclusionsOur analysis revealed that elevated CTI levels were significantly associated with CVD incidence and mortality. CTI may emerge as a unique predictive marker for CVD risk.
