BEAT-HTN India: Burden, Epidemiology, and Trends of Hypertension - A Nationwide Survey.

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 is a growing public health concern in India, increasingly interlinked with metabolic disorders such as diabetes and characterized by significant regional and demographic variation. Despite advancements in diagnosis and treatment, control rates remain unsatisfactory. Elevated resting heart rate (HR), an emerging marker of sympathetic overactivity, may offer additional insight into the underlying pathophysiology of Indian hypertensives. The objective of the study was to assess the prevalence of hypertension across India, explore its association with diabetes, elevated HR, and regional variation, and evaluate the potential role of sympathetic overdrive as a common pathophysiological thread. Methods: A nationwide, cross-sectional survey was conducted among 41,370 adults across 31 Indian regions. Data on systolic and diastolic blood pressure, resting HR, diabetes history, age, gender, and region were collected and analyzed to identify patterns of comorbidity and demographic distribution. Results: Overall hypertension prevalence was 29.8% (95% confidence interval (CI): 29.4 - 30.2), higher among males, 33.2% (95% CI: 32.6 - 33.8) than females, 27.2% (95% CI: 26.6 - 27.8). A notable proportion (14.6%, 95% CI: 14.2 - 15.0) of hypertensives also had diabetes, with this comorbidity more prevalent in males (15.8%, 95% CI: 15.2 - 16.4) than females (13.3%, 95% CI: 12.8 - 13.8). The mean resting HR was 83.9 bpm across all participants, exceeding 80 bpm even among normotensives, and was highest in diabetic hypertensives (85.9 vs. 82.2 bpm in non-diabetics; P < 0.05). Hypertension was more common in older adults, males, and those residing in urbanized or rapidly transitioning regions. Though obesity data were not captured, the strong associations between hypertension, diabetes, and elevated HR point toward underlying metabolic dysfunction and sympathetic overactivity. Conclusion: This large-scale survey reinforces the complex cardiometabolic burden in India and highlights elevated resting HR as a potential surrogate marker of sympathetic overactivity in hypertensives, especially those with diabetes. Regional and demographic disparities underscore the need for integrated, population-specific approaches that go beyond blood pressure control to address the broader spectrum of metabolic and autonomic dysfunction.
