Pellagra From Tryptophan Depletion in Carcinoid Syndrome due to a Pulmonary Atypical Carcinoid Neuroendocrine Tumor.
Article in Clinical case reports, 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
Pellagra may complicate functioning pulmonary atypical carcinoid and present as a subtle acral dermatosis rather than the classical photo-distributed rash. In neuroendocrine tumor patients with chronic diarrhea and new skin changes, clinicians should suspect niacin deficiency and consider empiric nicotinamide, even when niacin assays are unavailable.
