Patients' experiences with methylcobalamin injections in amyotrophic lateral sclerosis.
Article in Brain circulation. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
BACKGROUND AND
objectivesAmyotrophic lateral sclerosis (ALS) is a progressive motor neuron disease with no definitive treatment. Vitamin B12 is not a Food and Drug Administration-approved treatment in the United States, although it has been prescribed off-label as ultra-high-dose methylcobalamin, which has been shown to be safe and effective in slowing functional decline in patients with ALS. This study evaluates the impact of Vitamin B12 injections on the quality of life of five patients.
methodsSemi-structured interviews were conducted with the patients and caregivers. The data was carefully read, coded, and organized into themes and sub-themes by two independent researchers.
resultsThe study found four themes and 11 subthemes from the data, including initial circumstances, administration of the injection, subjective experience with Vitamin B12, and outcomes and expectations. All participants recognized some benefits from Vitamin B12 injections, specifically increased energy, reduced fatigue, and improved balance. However, some patients had difficulty monitoring its specific effect due to the progressive nature of the disease. DISCUSSION: The flexibility offered by this intervention is beneficial for patients with declining mobility and strength who wish to adapt their treatment to their schedule. This work is a modest call to fill the existing gap in the literature and push for more randomized controlled trials investigating and clarifying the effects of Vitamin B12 injections on disease progression, muscle function, and quality of life in a small but diverse pool of patients with ALS.
