Prevalence of elevated blood pressure and hypertension based on repeat measurements among school-going adolescents in Central India.
Article in BMC pediatrics, 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
backgroundScarcity of evidence regarding the need to obtain three separate Blood Pressure (BP) readings before diagnosing hypertension in adolescents exists in low middle income countries. Hence, this study aimed at determining the prevalence of elevated BP / hypertension in any two of the three visits among 10-18 years school-going adolescents. Secondly, to determine the trajectory of BP readings across age group, sex and over three visits.
methodsA longitudinal study was conducted across five urban schools of Bhopal district (Madhya Pradesh) among children aged 10-18-years. Multistage cluster sampling was adopted to cover a sample size of 780 over a one-year period. Those adolescents who satisfied the study criteria were checked for height and weight, followed by measurement of auscultatory BP readings on three different occasions, one week apart in each student. Three BP readings were obtained in each of the three settings at f-minute interval. The R shiny app was used to classify hypertension and compute systolic and diastolic percentiles.
resultsThe overall prevalence of elevated BP/hypertension in adolescents was 1.4% (N = 795), with 2.6% in boys and 0.2% in girls. There was a significant difference in the systolic and diastolic BP percentiles between boys and girls (N = 767) obtained during the second (P < 0.001) and third visit (P < 0.001). Also, significant changes in systolic and diastolic percentile across the three visits were observed (P < 0.001) (N = 767).
conclusionThe overall prevalence of elevated BP/HTN was one in hundred adolescents. Also, considering two out of three visits as a criteria for diagnosing HTN needs to be clarified and validated in a larger sample size and with further clinical follow-up to guide policymakers and suggest recommendations.
