1 · What the graph read from it

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.

2 · The registry

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

backgroundPneumorrhachis (PNR) is the presence of air within the spinal canal and may be either intramedullary or extramedullary in location. The etiology is most commonly iatrogenic or traumatic in nature. Treatment is dependent on underlying cause and physical exam. CASE DESCRIPTION: Herein, we describe the second case in the literature of spontaneous holocord PNR in a young patient without risk factors. A 22-year-old male with no past medical history presented to the hospital for 2 days of vomiting and cramping in his hands and feet secondary to severe dehydration. He recently started a new job as a manual laborer and had to leave work early 2 days prior due to overexertion working outside in heat ranging from 100 to 120 degrees Fahrenheit. CT abdomen and pelvis demonstrated spontaneous pneumomediastinum and extramedullary PNR extending upward from L3 throughout the thoracic spine to the upper limit of the scan. Subsequent CT cervical and thoracic spine showed the full length of the extradural air from C2-T12 and again at L3.

conclusionSpontaneous PNR is an uncommon, typically self-limited condition in which air is introduced into the spinal axis. Anatomic predisposition makes the extradural, dorsal cord in the cervicothoracic region the most common location. Patients are rarely symptomatic, and treatment is supportive in nature once secondary causes with high rates of morbidity and mortality are ruled out.
