Analysing risk factors for diabetes in Bangladesh: a Bayesian hierarchical approach using a nationwide cross-sectional study.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundBangladesh's diabetes burden is accelerating alongside rapid urbanisation and population ageing. Contemporary, population-representative risk estimates are needed to guide prevention.
methodsWe analysed 13,835 adults in the 2022 Bangladesh Demographic and Health Survey. Diabetes was defined as fasting plasma glucose [Formula: see text] 7 mmol/L or current use of diabetes medication. Associations with demographic, socioeconomic and clinical covariates were modelled using a Bayesian survey-weighted logistic mixed model with primary sampling unit random intercepts; design-unadjusted GLMM and survey-weighted GLM served as comparators. Posterior medians and 95% credible intervals (CrI) are reported.
resultsAge, adiposity and hypertension dominated the risk profile. Relative to 18-24 years, the odds of diabetes rose to 5.13 (4.22-6.24) for adults [Formula: see text] 65 years; overweight and obesity increased odds to 1.37 (1.22-1.53) and 1.78 (1.50-2.10), whereas underweight had lower odds at 0.80 (0.69-0.92). Hypertension conferred an odds ratio of 1.52 (1.35-1.70). Rural residence 0.75 (0.65-0.87) and residence in Rajshahi, Mymensingh or Khulna divisions ([Formula: see text] 0.55-0.66) were lower, while the richest wealth quintile carried higher risk at 1.77 (1.51-2.10). Model diagnostics were favourable: AUC = 0.79 indicates good discrimination; WAIC = 10,501 improved by [Formula: see text] 600 points versus the unweighted GLMM and survey-weighted GLM; and residual spatial autocorrelation was negligible (Moran's I = 0.06, p = 0.14).
conclusionsDiabetes in Bangladesh clusters among older adults, overweight/obese individuals, those with hypertension, and the socio-economically affluent, while remaining lower in rural and several northern divisions. Priority actions include age- and BMI-targeted screening, integrated hypertension-diabetes services, and urban lifestyle interventions, particularly in Dhaka and other high-prevalence regions. The Bayesian survey-weighted mixed-model framework yields policy-relevant, nationally generalisable estimates and offers a robust platform for tracking Sustainable Development Goal 3.4 indicators.
