The silent epidemic: unravelling NCD risk clusters and socioeconomic determinants in Zambia.
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
introductionNon-communicable diseases (NCDs) are a public health challenge in Zambia. This is driven by economic transitions, urbanization, and lifestyle changes. This study examines how NCDs cluster and relate to socioeconomic factors such as education, income, and employment. METHODOLOGY: Using data from the 2017 Zambia WHO STEPS survey (N = 4,302 adults, mean age: 36.57 years), Latent Class Analysis identified NCD risk profiles, and multinomial logistic regression assessed their associations with socioeconomic determinants.
resultsThree NCD risk groups emerged: Low-Risk (12.0%), Intermediate-Risk (64.3%), and High-Risk (23.7%). The Low-Risk group maintained healthy lifestyles. The Intermediate-Risk group, the most prevalent, showed borderline metabolic indicators and occasional unhealthy behaviours. The High-Risk group exhibited multiple risk factors, including obesity, hypertension, diabetes, and substance use. Males had 22.8 times higher odds of being in the High-Risk group than females. Surprisingly, higher education increased the odds of being in the Moderate- and High-Risk groups.
conclusionNCD prevention in Zambia requires risk-stratified strategies: primary prevention for Intermediate-Risk groups and intensive intervention for High-Risk populations. Critical policy actions include taxing tobacco, alcohol, and unhealthy foods; expanding universal screening; integrating NCD care into primary health systems; and addressing urbanization, cultural practices, and healthcare disparities.
