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 (CRP)-triglyceride glucose index (CTI) is a new composite biomarker used to assess inflammation and insulin resistance (IR) severity. Inflammation and IR play important roles in chronic obstructive pulmonary disease (COPD). However, the impact of CTI on COPD remains unknown.

methodsTo explore the association between CTI and the prevalence of COPD, a total of 8682 participants from the China Health and Retirement Longitudinal Study (CHARLS) and 8986 participants from the US National Health and Nutrition Examination Survey (NHANES) were included. We used logistic multivariate regression to evaluate the association between CTI and COPD. In addition, smooth curve fitting analyzed dose-response relationships, while subgroup analyses explored effect heterogeneity.

resultsWe found a positive correlation between CTI and the risk of COPD after adjusting for all covariates in the NHANES database (OR = 1.34, 95% confidence interval [CI]: 1.18-1.53), which is consistent with the findings obtained from Cox regression analysis in the CHARLS database (HR = 1.16, 95% CI: 1.07-1.26), with consistent dose-response trends confirmed by restricted cubic spline (RCS) analyses. Subgroup analyses confirmed consistency across most strata, with a significant interaction detected with cardiovascular disease (CVD). Sensitivity analyses further confirmed the robustness of associations.

conclusionsThese findings indicate a significant association between CTI and COPD, suggesting its potential role as a biomarker for the prevention and treatment of COPD.
