Waist-to-height ratio and hypertension risk: a retrospective cohort analysis of the CHARLS.
Article in BMC cardiovascular disorders, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundHypertension represents a significant global health concern, with central obesity widely acknowledged as a pivotal risk factor. The objective of this study was to investigate the association between waist-to-height ratio (WHTR) and hypertension risk, identify specific thresholds.
methodsWe analyzed data from 7,712 participants of the China Health and Retirement Longitudinal Study (CHARLS), aged ≥ 45 years and free of hypertension at baseline (2011–2012),with follow-up until 2020. Waist-to-height ratio (WHtR) was the primary exposure and incident hypertension the main outcome. Covariates included demographic, lifestyle, and metabolic factors. To flexibly model the association between WHtR and hypertension risk, we used restricted cubic spline regression. Threshold effect analysis was conducted using two-piecewise linear regression, with the inflection point determined via log-likelihood maximization and assessed using the likelihood ratio test.
resultsThere was a non-linear association between WHtR and incident hypertension, with an inflection point (cut point) at WHtR = 0.443. Below this threshold, higher WHtR was not associated with increased risk of hypertension (HR = 0.79, 95% CI: 0.71–0.89). However, above the cut point, each 0.1-unit increase in WHtR was associated with an 82% increased risk of developing hypertension (HR = 1.82, 95% CI: 1.68–1.96). The risk difference before and after the cut point was statistically significant (HR = 2.28, 95% CI: 1.96–2.66).
conclusionHigher WHtR is independently associated with a greater risk of hypertension in Chinese adults. The optimal cut-off identified in our cohort (0.438) is lower than commonly used Western thresholds. Population-specific cut-offs may improve screening and prevention efforts.
