Using waist circumference as a predictor of hypertension in Manzese, Dar es Salaam: a community-based cross-sectional study, 2023.

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
introductionIt is estimated that 1.3 billion people in the world have hypertension and a large proportion of them are unaware. Waist circumference has emerged as Potential predictor of Cardiovascular Diseases (CVD) risk; however, fewer studies in Tanzania have evaluated its role in screening for CVD risk. This study aimed to determine the role of waist circumference in screening for hypertension, a major risk for CVD.
methodsAn analytical cross-sectional study was conducted in Manzese ward, Dar es Salaam, from August to September 2023. Adults who attended a screening campaign were systematically randomly sampled. Data were collected using WHO STEPwise Approach to Chronic Disease Risk Factor Surveillance questionnaire. The relationship between waist circumference and hypertension was analyzed using a Modified Poisson regression model with robust standard errors.
resultsAmong 561 participants screened, 70.4% were female, with a median age of 47 years (IQR: 34-58). The overall prevalence of hypertension was 45.8% (95% Confidence interval [CI]: 41.7-49.9). Those with elevated waist circumference had a 34% higher likelihood of hypertension (adjusted prevalence ratio [aPR] 1.34, 95% CI: 1.03-1.73, P = 0.027). Participants aged 35 and above were 160% more likely to be hypertensive (aPR 2.6, 95% CI: 1.79-3.78, P < 0.001). A family history of hypertension increased the likelihood by 31% (aPR 1.31, 95% CI: 1.08-1.59, P = 0.006).
conclusionThis study reveals a high prevalence of hypertension among Manzese residents, with key risk factors including elevated waist circumference, age ≥ 35 years and a family history of hypertension. The strong association between waist circumference and hypertension suggests that incorporating waist measurement into cardiovascular risk assessment could enhance early detection and improve prevention efforts. This practical and cost-effective approach may improve the identification of at-risk individuals, enabling timely interventions and reducing the long-term burden of hypertension-related complications.
