Persistent Multiple Colonic Ulcers and Repeated Acute Bloody Diarrhea in an Elderly Patient with Transthyretin Amyloidosis: A Case Report.
Article in Cureus, 2024. 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
The clinical gastrointestinal manifestations of transthyretin amyloidosis (ATTR amyloidosis) are usually non-specific, and colonic bleeding or ulcers are unusual. Here, we report the case of an elderly Japanese man with ATTR amyloidosis who presented with rare gastrointestinal symptoms. An 84-year-old Japanese man was referred to our hospital because of anemia and positive fecal occult blood test results. Endoscopic examination revealed multiple small colonic erosions and/or ulcers; however, the cause remained unknown. The patient repeatedly visited our hospital for one year because of acute bloody diarrhea, anemia, and multiple persistent colonic ulcers. His symptoms improved after symptomatic treatment. The most recent gastric biopsy revealed ATTR amyloidosis, which was retrospectively detected in colon, stomach, and gallbladder specimens obtained six months, six years, and 12 years earlier, respectively. Therefore, ATTR amyloidosis should be considered in the differential diagnosis of colon-related anemia.
