Prehypertension, Hypertension, and Their Association With Weight-Adjusted Waist Index in Normoglycemic Japanese Adults: A Cross-Sectional Study.

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
objectiveObesity, impaired glucose tolerance, and diabetes significantly increase hypertension risk. Previous studies across various populations have linked the weight-adjusted waist index (WWI)-a key indicator for assessing obesity-to hypertension. However, this relationship remains unclear specifically in non-diabetic populations, particularly normoglycemic individuals. Focusing on normoglycemic Japanese adults, the present study explored the correlation of WWI with prehypertension or hypertension.
methodsData sourced from the program for medical screening at Murakami Memorial Hospital (Japan) were subjected to secondary analysis, which included 15,464 participants. To quantify the relationship of the WWI with prehypertension (pre-HTN) or hypertension (HTN), multivariable logistic regression analyses were applied. Restricted cubic spline (RCS) models were further applied to evaluate the dose-response relationship of WWI with the two outcomes. Subgroup analyses were also conducted.
resultsAmong 15,453 normoglycemic Japanese adults, the mean WWI increased progressively across blood pressure categories (normal < prehypertension < hypertension). Following adjustment for key confounding variables, WWI was independently correlated with prehypertension (OR = 1.50, 95% CI: 1.39-1.61, p < 0.001) and hypertension (OR = 1.74, 95% CI: 1.51-2.00, p < 0.001). Curve Fitting confirmed a linear, monotonic positive correlation of WWI with both outcomes (all p values for non-linearity tests > 0.05). Subgroup analyses revealed a stronger association between WWI and prehypertension in females, individuals without fatty liver disease, and current smokers.
conclusionsOur study demonstrated a positive linear correlation of WWI with both prehypertension and hypertension risk in normoglycemic Japanese individuals.
