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
Vitamin B12 (cobalamin) deficiency is a commonly seen nutritional deficiency that presents with a broad spectrum of clinical symptoms. In this report, we describe a case of a 49-year-old female patient who presented to the emergency department with sudden onset of a syncopal-like episode, generalized weakness, and severe pancytopenia, who was subsequently diagnosed with vitamin B12 deficiency upon admission. The patient underwent a thorough evaluation to exclude alternative etiologies for her presentation. Her clinical symptoms and blood count significantly improved after six days of treatment with vitamin B12 supplementation. While vitamin B12 deficiency is a commonly recognized issue, healthcare providers should be aware of its infrequent presentations. Our case serves as a reminder to clinicians to remain vigilant for acute onset manifestations and consider vitamin B12 deficiency as a differential diagnosis for the early management of pancytopenia.
