Postpartum peripheral neuropathy due to vitamin B12 deficiency, potentially precipitated by nitrous oxide use.
Article in Anaesthesia reports. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Neurological dysfunction which would concern the anaesthetist on labour ward is typically associated with neuraxial blocks. However, an appreciation of other causes is crucial. We present a case of peripheral neuropathy secondary to vitamin B12 deficiency, which highlights the importance of a thorough neurological examination, alongside an understanding of neurological pathophysiology. This is crucial for initiating appropriate referral, subsequent investigations and treatment. Neurological dysfunction secondary to vitamin B12 deficiency may be reversible, following prolonged rehabilitation, so prevention is the best approach, which may require modification of anaesthetic techniques. In addition, at-risk patients should be screened and treated prior to nitrous oxide use, with alternative methods of labour analgesia advised in very high-risk individuals. The incidence of vitamin B12 deficiency may increase in the future potentially linked to a rise in plant-based diets, so this picture may be more commonly seen. Added vigilance by the anaesthetist is imperative.
