Predictive factors for hypertensive encephalopathy in hospitalized pediatric patients: a retrospective case-control study.

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
backgroundHypertensive emergency in children often exhibits neurological symptoms indicative of hypertensive encephalopathy (HE). The risk factors concerning HE development remain unclear, motivating the objective of this study to identify risk factors and formulate an equation for forecasting HE in hospitalized pediatric patients.
methodsThis retrospective case-control study focused on pediatric patients aged 1-18 years diagnosed with hypertension from 2011 to 2021. Logistic regression analysis was utilized to identify variables associated with HE. A HE predictive equation was developed based on significant factors, with sensitivity, specificity, and predictive values assessed using receiver operating characteristics curves.
resultsThree hundred thirty-two patients with mean age 9.3 years were recruited. 12.3% developed HE. Univariable analysis revealed risk factors for HE, including central nervous system symptoms, peak systolic and diastolic blood pressure z-score (Z-SBP and Z-DBP), corticosteroid and calcineurin inhibitor use, and leukemia/lymphoma. Logistic regression formed the equation predicting HE occurrence as follows: 2.162 (vomiting) + 2.921 (headache/dizziness) + 2.363 (leukemia/lymphoma) + 1.807 (corticosteroid) + 0.783 (peak Z-SBP). The equation demonstrated robust correlation with predicted probability of developing HE and had AUC of 0.95. A cutoff score of 4 showed high sensitivity (97.6%) and negative predictive value (99%), identifying 98% of HE cases.
conclusionsThis study pinpointed key risk factors and introduced an accurate predictive equation, underscoring the significance of assessing multiple factors beyond blood pressure levels for HE prediction in hypertensive pediatric patients.
