Pyoderma gangrenosum-like lesion secondary to methylenetetrahydrofolate reductase mutation: an unusual presentation of a rare disease.
Article in BMJ case reports, 2019. 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
Pyoderma gangrenosum (PG)-like ulcerations are a rare clinical manifestation of methylenetetrahydrofolate reductase (MTHFR) mutation. We describe a patient considered to have PG who was treated with long-term high doses of systemic corticosteroids and multiple immunosuppressive agents for several years. In spite of this continuous aggressive therapy, the lesions did not improve but continued to get worse. She developed many significant and catastrophic side effects to them. When referred to our dermatology centre, on investigation, it was discovered that she has an MTHFR mutation. It seemed reasonable to presume that PG-like lesions were related to it. Treatment with a biologically active form of folate-[6S]-5-MTHF-with vitamins B6 and B12 was initiated. It was considered to be beneficial and capable of reducing hyperhomocysteinaemia and endothelial damage consequent from it. Since the institution of this treatment, the patient has begun to show very gradual but slow and incremental improvement.
