A Case of Subacute Degeneration of the Spinal Cord Due to Vitamin B12 Deficiency Triggered by Nitrous Oxide Use.

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
In this case report, we discuss a young female who presented to the emergency department with a recent onset of weakness, paraesthesia, and gait disturbance suggestive of peripheral neuropathy and gait ataxia. This was attributed to the occasional use of recreational nitrous oxide (N2O) over the past 10 months. Subacute combined degeneration of the spinal cord is a condition affecting the lateral and posterior columns of the spinal cord, mainly caused by demyelination. The use of recreational N2O depletes the levels of vitamin B12 thus leading to this demyelination of the nervous system. Physical examination revealed T6 and T7 and L3 and L4 sensory deficits bilaterally with hyporeflexia in bilateral knee and ankle reflexes with reduced power in the left lower limb as well as a spastic gait. Her vitamin B12 levels were low (98 g/dL). MRI spine showed a high signal in the posterior cord/ dorsal column. The patient made good recovery post-intramuscular B12 administration and physiotherapy with planned outpatient neurology rehabilitation.
