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 a prevalent issue in daily life, and previous studies have demonstrated a correlation between inflammation and obesity. Additionally, some studies have investigated the relationship between inflammation and body mass index, a widely used indicator of obesity. In recent years, the weight-adjusted waist circumference index (WWI) has been introduced and increasingly utilized in the clinical assessment of obesity and overweight. However, its relationship with the inflammatory marker α1-acid glycoprotein (AGP) remains unclear. In this study, we analyzed data from 2899 adult women (mean age 33.42 ± 9.27 years) from the National Health and Nutrition Examination Survey (2015-2020). The WWI was calculated as the square root of waist circumference divided by body weight. Multiple linear regression analysis and smooth curve fitting were performed to validate the results. Finally, the relationship between WWI, AGP, and various clinical factors, including educational status, age, and hypertension incidence, was analyzed. Subgroup analysis and interaction tests were performed during the analysis. This study included 2899 adult female participants (mean age 33.42 ± 9.27 years). The mean levels of WWI and AGP were 10.97 ± 0.83 and 0.79 ± 0.24 g/L, respectively. In the fully adjusted model, multiple linear regression analysis revealed a significant positive correlation between WWI and AGP levels, with each unit increase in WWI associated with a 0.06 g/L increase in AGP (β = 0.06, 95% CI: 0.05-0.07). When WWI was categorized into quartiles, AGP levels in the highest quartile were 0.13 g/L higher than those in the lowest quartile (β = 0.13, 95% CI: 0.10-0.15). Moreover, smooth curve fitting identified an inflection point in this relationship at a WWI value of 11.78. In the adult female population in the United States, WWI and AGP exhibited a significant positive correlation.
