Bedside Multimodal Ultrasonography for the Detection of Intracranial Hypertension in Severe Adolescent Preeclampsia: A Case Report and Screening Proposal.
Article in Cureus, 2026. 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
Preeclampsia is a leading cause of maternal morbidity and mortality worldwide and is frequently complicated by cerebral edema and elevated intracranial pressure (ICP). Noninvasive neuromonitoring tools such as transcranial Doppler (TCD) and ocular ultrasonography may help detect intracranial hypertension before overt neurological deterioration. We report a 17-year-old primigravida at 34 weeks of gestation who presented with severe preeclampsia and a hypertensive crisis, but without focal neurological deficits. Laboratory tests confirmed severe preeclampsia, and an emergency caesarean section was performed with a good neonatal outcome. Postoperatively, bedside TCD of the middle cerebral artery showed an elevated pulsatility index (PI = 1.25) and resistance index (RI = 0.68). At the same time, ocular ultrasound demonstrated an enlarged optic nerve sheath diameter and optic disc protrusion, both consistent with increased ICP despite the patient's normal neurological exam. This case illustrates the potential role of combined TCD and ocular ultrasonography for early, noninvasive assessment of intracranial hypertension in severe preeclampsia, particularly in adolescent patients. We propose a two-step bedside ultrasound protocol to identify subclinically elevated intracranial pressure.
