1 · What the graph read from it

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.

2 · The registry

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

backgroundHypertension, the leading risk factor for cardiovascular diseases, remains largely undiagnosed in low-resource settings. This study focuses on the hidden crisis of undiagnosed hypertension among women of reproductive age with elevated blood pressure (BP) in Tanzania, where up to 90% remain unaware of their condition.

methodsUsing data from the 2022 Tanzania Demographic and Health Survey and Malaria Indicator Survey (TDHS-MIS), this cross-sectional study analyzed a nationally representative sample of 853 women aged 15–49 years with elevated BP. Hypertension was defined as an average systolic blood pressure (SBP) ≥ 140 mmHg, diastolic blood pressure (DBP) ≥ 90 mmHg, or current antihypertensive medication use. Undiagnosed hypertension was categorized based on self-reported lack of prior diagnosis. Multilevel logistic regression was employed to identify determinants at individual and community levels, while forest plots assessed regional disparities.

resultsThe prevalence of undiagnosed hypertension was 77%. Regional disparities were evident, with the Western (90%) and Central (89%) zones showing the highest prevalence, these zonal estimates are elevated because key regions within them report very high proportions, Tabora (97%) and Dodoma (90.5%) respectively. In contrast, Zanzibar had the lowest prevalence at 48%. With each additional year of age, the odds of being undiagnosed decreased by 8.0% (AOR: 0.92, 95% CI: 0.89–0.95), while married women (AOR: 0.21, 95% CI: 0.08–0.59)women with internet access (AOR: 0.32, 95% CI: 0.15–0.69) and women from wealthier households all had significantly lower odds of undiagnosed hypertension ((middle (AOR: 0.32, 95% CI: 0.16–0.67)) and ((higher socioeconomic classes (AOR: 0.37, 95% CI: 0.17–0.80)). Community-level variation accounted for 25–32% of disparities, with a Median Odds Ratio (MOR) of up to 3.30, indicating substantial contextual influence.

conclusionsThe high prevalence of undiagnosed hypertension among Tanzanian women highlights the urgent need for targeted interventions. Improving health awareness, integrating screening into primary care, and addressing regional inequities can significantly reduce this burden and improve maternal and cardiovascular health outcomes.
