IgG4-Producing MALT Lymphoma in the Renal Hilum.
Article in Case reports in oncology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
IgG4-related disease is diagnosed when both the elevation of the serum IgG4 level and invasion of IgG4-positive interstitial cells and sclerosis to a tumor are noted. Some cases have demonstrated malignant disease. In the head and neck lesion in particular, IgG4-producing mucosa-associated lymphoid tissue (MALT) lymphoma has arisen during the treatment of IgG4-related disease. We herein report the first case of IgG4-producing MALT lymphoma during the treatment of IgG4-related disease in the renal hilum. A 79-year-old man was being followed for autoimmune pancreatitis and IgG4-related sclerosing cholangitis. During follow-up, magnetic resonance cholangiopancreatography detected a mass in the renal hilum, so he was referred to our department for a further examination. Positron emission tomography-computed tomography detected a standard uptake of 9.7, and the tumor size was gradually increasing. Due to these findings, laparoscopic nephro-ureterectomy was performed. A pathological examination revealed IgG4-producing marginal zone B cell lymphoma. We herein report a rare case of IgG4-producing B cell lymphoma in the renal hilum.
