Head-to-head comparison of visceral adiposity indices (A Body Shape Index and Visceral Adiposity Index) with traditional anthropometrics: a community-based strategy for cardiovascular risk prediction in urban China.

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
objectivesThis study aimed to compare the predictive performance of novel adiposity indices (a body shape index (ABSI) and visceral adiposity index (VAI)) with traditional anthropometrics (body mass index (BMI), waist circumference (WC) and waist-to-height ratio (WHtR)) for cardiovascular disease (CVD) risk in urban China. Secondary objectives included evaluating composite indices derived from principal component analysis (PCA) and evaluating optimised risk stratification strategies.
designA community-based cross-sectional study.
settingUrban and rural communities in Nanjing, China, from 2020 to 2023.
participants38 427 adults aged 35-79 years, recruited via stratified sampling. Individuals aged <35 or >79 years, who were pregnant or had severe illness or cognitive impairment were excluded. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was a CVD high-risk status (defined by Chinese guidelines). Secondary outcomes included detection rates, area under the curve (AUC), ORs and multicollinearity diagnostics.
resultsAmong participants, 23.3% (n=8905) were classified as high risk for CVD. In this study, WHtR demonstrated the greatest discriminative power (AUC=0.826, 95% CI 0.819 to 0.832), followed by a PCA-derived composite obesity index (COI; AUC=0.822). ABSI showed a clear risk gradient, with a 38.5% detection rate in the high-risk group (ABSI≥0.085), and VAI exhibited a modest but statistically significant effect (OR=1.026, p=0.001). Severe multicollinearity among traditional indices (variance inflation factor >40) was mitigated by COI. Combined models (eg, COI+ABSI+ VAI) achieved comparable AUC (0.825) with improved parsimony (AIC=17 4010.34). Age, hypertension and dyslipidaemia were key covariates (ORs=1.15-3.88, p<0.001).
conclusionsWHtR and composite indices (eg, COI) appeared to perform better than other indicators in predicting CVD risk, whereas ABSI and VAI enhance stratification in specific subgroups. Implementing WHtR-based screening in primary care, supplemented by composite indices and novel markers for high-risk individuals, may help optimise prevention strategies in urbanising Chinese populations.
