Vitamin B12 deficiency: testing and treatment.
Review in Australian prescriber, 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
Vitamin B12 testing is recommended for individuals with clinical signs and symptoms suggestive of B12 deficiency, and when there is reasonable clinical suspicion of deficiency due to risk factors (e.g. inadequate dietary intake, malabsorptive conditions). Where vitamin B12 testing is indicated, total serum B12 is typically the first-line test. Active B12 may be requested if total B12 results are indeterminate, or during pregnancy. If total or active B12 tests are inconclusive, methylmalonic acid or homocysteine testing may be considered; however, their concentrations may be elevated in other conditions. In individuals with confirmed B12 deficiency, B12 supplementation is required, with the choice of formulation, duration and dosage guided by the underlying cause and severity of the deficiency and patient preference.
