A Rare Cause of Vitamin B12 Deficiency in the Pediatric Age.
Article in Cureus, 2024. 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
Vitamin B12 plays an important role in DNA synthesis, hematopoiesis, and neuronal mechanisms, and its deficiency can be associated with insufficient intake or poor absorption and autoimmune and genetic diseases. Although rare, excessive, and chronic alcohol consumption may also justify a deficiency in this vitamin. We present a case of a 17-year-old Iraqi adolescent refugee in Portugal with a deficiency of vitamin B12 due to excessive and chronic alcohol consumption. Although intramuscular (IM) supplementation with cyanocobalamin is the most used, it was decided to initiate oral supplementation. After four months, vitamin B12 levels were replenished. With this clinical case, we aim to raise awareness of the cause of cyanocobalamin deficiency, which although rare in pediatric age should be considered in adolescents, given the possibility of risky behaviors in this age group. Additionally, given the therapeutic options, we have found that oral administration of vitamin B12 has been effective, as reported in the literature.
