Hypertensive Emergencies in the Ambulance: Characteristics, Clinical Presentations and Complications - A Prospective Cohort Study.
Article in Open access emergency medicine : OAEM, 2021. 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
backgroundThe objective of this study is to describe the characteristics of hypertensive emergencies in Kuwait aiming to provide a preliminary background to update the current guidelines and improve patients' management.
methodsThis is a prospective analysis of hypertensive emergency cases retrieved from emergency medical services (EMS) archived data between 1 January - 30 June 2020. Collected variables included patient characteristics, clinical presentations, vital signs, interventions, and complications. Outcome variable collected was: en route complications.
resultsHypertensive emergency prevalence in Kuwait is 4.75 per 100,000. Most were non-Kuwaiti (62%) males (59%) with a mean age of 57 ±14 years. Most hypertensive emergency cases occurred at home (62%). The hypertensive emergency BP threshold was; SBP 182 (SD=31) and diastolic BP (DBP) 108 (SD=18). 36% of hypertensive emergency cases had silent hypertension. 67% of hypertensive emergencies were verified using ambulance verification tools. Nitroglycerin was administered to only hypertensive emergencies suspected to have acute coronary syndrome or acute heart failure (50%). Complications were seen in 9.5% of hypertensive emergency cases.
conclusionHypertensive emergency is rare in the ambulance but can progress into a serious situation. One in every 10 hypertensive emergency cases will require en route resuscitation. Hypertensive emergencies should be recognized and managed within their clinical context. The most common clinical presentation of hypertensive emergency is cardiac chest pain. Some pre-hospital verification tools confirm acute HMOD. Further research is required to establish hypertension emergency recognition and management guidelines in the prehospital setting.
