Evaluating the Hypertension Cascade of Care in Adults in Urban Lao PDR: Evidence From the VITERBI Cohort Study.
Article in Vascular health and risk management, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Hypertension (HT) is a major risk factor for adult morbidity and mortality in low- and middle-income countries and little is known regarding the distribution of HT risk and treatment access within urban areas. Patients and methods: We used data from the Vientiane Multi-Generational Birth Cohort in urban Lao PDR to assess the prevalence of loss and retention across five stages of HT care for 40+ year old adults: i) prevalence of hypertension, ii) hypertensives who ever had their BP measured by a health care professional, iii) hypertensives ever diagnosed with HT by a professional, iv) patients currently treated with HT medication, and v) patients with currently controlled BP. We estimated associations between sociodemographic and lifestyle predictors and the proportion of participants who reached each care cascade step using mutually adjusted Poisson regression modeling. Results: Among the 3196 participants aged 40 to 99 years, the overall prevalence of HT was 16.3%, with higher rates for women, people over 60 years, peripheral district residents, low educated, widowed, and obese. Among people with HT, 90.2% ever had their BP measured by a health care professional, 69.3% ever received a HT diagnosis, 60.9% HT were currently on (drug) treatment, and 39.5% had currently controlled BP. The largest cascade of care losses occurred at the diagnosis and control stages with better outcomes for women. While central districts showed higher rates of diagnosis, control levels were lower than in peripheral districts, but there these differences appeared to be explained by adjusting for sociodemographic and lifestyle factors. Conclusion: While HT prevalence in Lao PDR is lower than reported for other LMICs, more than 16% over the age of 40 years suffer from HT, and 60% of these cases are currently not controlled. Major policy efforts are needed to support this population and to prevent HT-driven excess mortality.
