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
backgroundMethylmalonic acidaemia with homocystinuria type C (cblC defect) is an inherited error of cobalamin metabolism. Cobalamin deficient processing results in high levels of methylmalonic acid and homocysteine. The latter is considered to be a risk factor for multiple sclerosis (MS). We report on the first case of a patient with comorbid cblC defect and MS. CASE REPORT: This young male presented at the age of 14 with a relapsing-remitting neurological disorder associated with imaging alterations suggestive of MS. Treatment resulted in a partial clinical improvement with vanishing of white matter lesions. Later on, the emergence of unexpected clinical features led to a metabolic work-up, revealing a cobalamin intracellular defect. Genetic analysis disclosed a single variant in DISCUSSION: While the comorbid association of MS and cblC in our patient may remain anecdotic, we suggest measuring Hcy and MMA levels in young patients with a relapsing-remitting demyelinating disorder, in order not to miss a cblC defect, that requires a specific and effective treatment.
