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
backgroundParoxysmal hypertension can be associated with failure of the carotid artery baroreceptors due to past exposure to radiation treatment. This report describes a patient whose repeated paroxysmal hypertensive episodes were ameliorated following placement of a carotid artery stent for the treatment of carotid artery stenosis. CASE REPORT: A 79-year-old caucasian male was diagnosed with hypopharyngeal squamous cell carcinoma (T1, L0, M0) in 2006, and received 70 Gy intensity-modulated radiotherapy in 2006 and underwent a total laryngectomy in 2008. He experienced paroxysmal hypertensive episodes since 2010 that exacerbated in frequency in 2019. Eighty percent left internal carotid artery stenosis was demonstrated by ultrasound and arteriography. Angioplasty and stenting of the left carotid artery was performed. A Doppler ultrasound study performed 5 months after the stent placement did not reveal any hemodynamic stenosis in the left carotid artery. The patient experienced postprandial hypotension and had experienced only three episodes of paroxysmal hypertension in the following 24 months. He was able to abort paroxysmal hypertensive episodes by eating warm food. DISCUSSION: This is the first report of a patient whose paroxysmal hypertensive episodes that occurred following radiation of the neck subsided after placement of a stent in a stenotic carotid artery. The exact mechanism leading to this phenomena is unknown but may be due to several factors. The reversal of the carotid artery stent and improvement in blood flow to the carotid artery baroceptors may play a role in this phenomenon.
conclusionThe ability to ameliorate paroxysmal hypertensive episodes in a patient with carotid artery stenosis by stent placement may be a promising therapeutic intervention for paroxysmal hypertension.
