Accuracy of blood pressure-to-height ratio for the identification of elevated blood pressure in children: A cross-sectional study.
Article in Journal of family & community medicine. 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
backgroundThere is little evidence to show that the blood pressure-to-height ratio (BPHR) accurately detects elevated blood pressure (EBP) in children. The present study evaluated the accuracy of BPHR in detecting EBP in children aged 8-11 years. MATERIALS AND
methodsThis cross-sectional study involved 1087 children (531 boys and 556 girls), aged 8-11 years. Weight, height, and blood pressure (BP) were measured using the standard procedure. EBP was defined as systolic or diastolic pressure at the 90th percentile or above at a specific gender, age, and height. Mann-Whitney U test and Spearman's correlation were applied. The diagnostic accuracy was set at an area-under-the-curve of ≥0.90. Sex-specific cutoff points for systolic BPHR (SBPHR) and diastolic BPHR (DBPHR) were determined. The sensitivity and specificity of SBPHR and DBPHR were also determined.
resultsMost variables between sexes were comparable (P > 0.05), except weight, height, and body mass index (BMI) in the 8-9 years' age group. Almost all variables for children with EBP were significantly higher than normotensive (P < 0.05). SBPHR correlated with all variables except BMI in girls. DBPHR correlated with almost all variables except age (sexes) and height (girls). The accuracy of SBPHR and DBPHR in diagnosing EBP in both sexes was above 95%. The optimal threshold of SBPHR and DBPHR for diagnosing EBP was 0.804/0.519 in boys and 0.831/0.530 in girls. The sensitivity and specificity were 90.8%-96.5% and 86.0%-93.2%, respectively.
conclusionSBPHR and DBPHR have high accuracy, sensitivity, and specificity in detecting EBP in Indonesian children aged 8-11 years.
