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
backgroundThe rapidly growing burden of non-communicable diseases (NCDs) in sub-Saharan Africa necessitates a better understanding of access gaps along the care continuum. This study assessed the prevalence and inequality in unmet need for hypertension and diabetes care in Tanzania, South Africa, and Lesotho using a care cascade framework.
methodsWe conducted a cross-sectional analysis of nationally representative Demographic Health Survey (DHS) datasets from Tanzania (2022), South Africa (2016), and Lesotho (2023/24), focusing on adults aged 15 years and older. The study estimated the proportion of adults with hypertension or diabetes who had not been screened, diagnosed, treated, or achieved disease control. Inequality was assessed using Erreygers Normalized Concentration Indices (ENCI), stratified by sex and residence.
resultsHypertension prevalence was 12.6% (95% CI: 11.7-13.4) in Tanzania, 46.7% (95% CI: 45.0-48.4) in South Africa, and 15.4% (95% CI: 13.8-17.2) in Lesotho. In Lesotho, 9.1% (95% CI: 7.8-10.6) of adults had diabetes. Unmet need was substantial across all countries: 96.5% for hypertension in Tanzania, 84.2% in South Africa, 65.8% in Lesotho, and 84.2% for diabetes in Lesotho. The care cascade framework revealed critical bottle-necks at screening and treatment stages. Inequality analyses revealed strong pro-poor gradients, particularly in screening (ENCIs: Tanzania -0.19, South Africa -0.17, Lesotho hypertension -0.15, Lesotho diabetes -0.24; all
conclusionSubstantial and inequitable gaps exist in hypertension and diabetes care. Policy strategies should prioritize community-based screening, primary care integration, and equity-focused interventions targeting poor men to improve NCD outcomes in the region.
