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

Obesity is more prevalent in women worldwide and has been associated with low-grade inflammation, oxidative stress, and alterations in the homeostasis of trace elements, such as zinc (Zn) and copper (Cu). The aim of this study was to evaluate the association between nutritional status and cardiometabolic traits, inflammatory biomarkers, oxidative stress markers, and serum concentrations of Zn and Cu in adult women. In this observational cross-sectional study, anthropometric data and cardiometabolic traits from 123 adult women in Mexico City were analyzed. Inflammatory biomarkers (leptin and resistin) were quantified by enzyme-linked immunosorbent assay (ELISA). Oxidative stress markers were evaluated by serum total antioxidant capacity (sTAC) using the DPPH radical scavenging method (2,2-diphenyl-1-picrylhydrazyl) and lipid peroxidation via thiobarbituric acid reactive substances (TBARS). Serum Zn and Cu concentrations were quantified by inductively coupled plasma mass spectrometry (ICP-MS). Overweight and obesity were associated with increased lipid peroxidation (p = 0.013) and the Cu/Zn ratio (p = 0.021) and negatively associated with sTAC (p = 0.030) and Zn concentrations (p = 0.003). A positive association was observed between serum Cu concentrations and total cholesterol (TC; p = 0.045). Leptin and resistin concentrations were higher in the overweight and obesity groups. In conclusion, our findings suggest that higher body weight in Mexican adult women is associated with a deregulated redox status and trace elements homeostasis, particularly reduced Zn levels and an increased Cu/Zn ratio. Additionally, the observed association between serum Cu concentrations and TC may highlight a potential mechanism linking adiposity, oxidative stress, and lipid metabolism.
