Vitamin B12 Deficiency Presenting as Anemia and Functional Decline in an Older Adult: A Case Report.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Anemia is a common condition in older adults and is associated with increased morbidity, geriatric syndromes, and functional decline. We report the case of an 86-year-old woman who presented with severe anemia accompanied by neurologic, hematologic, and oral manifestations, in whom vitamin B12 deficiency was identified as the underlying etiology. Following targeted parenteral cyanocobalamin therapy, the patient demonstrated marked hematologic recovery and substantial improvement in gait, strength, and independence in basic activities of daily living, as documented through a comprehensive geriatric assessment. This case underscores the importance of recognizing vitamin B12 deficiency as an underdiagnosed yet reversible cause of anemia and functional deterioration in older adults and highlights the essential role of comprehensive geriatric assessment in detecting reversible contributors to frailty and enabling timely, individualized intervention.
