Gastric antral vascular ectasia in a pediatric patient with neuroblastoma who underwent tandem stem cell transplantation.

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
Gastric antral vascular ectasia (GAVE) is an angiodysplastic disorder, which causes severe and prolonged gastric bleeding. Although GAVE has been described in adult patients treated with hematopoietic stem cell transplantation (HSCT), a few cases involving pediatric patients have also been reported. A 5-year-old boy with neuroblastoma (NB) developed severe hematemesis after undergoing tandem HSCT, i.e. autologous peripheral blood stem cell transplantation (auto-PBSCT), followed by allogeneic cord blood transplantation (allo-CBT). The patient suffered oral feeding difficulties because of the effects of chemotherapy and an unbalanced diet. Intravenous Busulfan (ivBU) was used as a conditioning regimen for the auto-PBSCT. The diagnosis of GAVE was made based on endoscopy of the upper gastrointestinal tract on day 31 after the allo-CBT. Argon plasma coagulation (APC) was performed twice, and the complete resolution of GAVE was confirmed by an endoscopic re-evaluation, conducted on day 87. GAVE in this case might have been associated with ivBU treatment. Atrophy of the gastric mucosa due to loss of appetite might also have contributed to GAVE. NB was treated using high-doses of alkylating agents, such as BU. Such treatment can cause significant mucositis of the oral cavity as well as vascular lesions and is associated with GAVE. Therefore, GAVE should be considered when gastrointestinal bleeding occurs in NB patients treated with HSCT. APC might be effective against HSCT-GAVE.
