Microscopic polyangiitis masquerading as a pancreatic neoplasm with multiple lung metastases.
Article in BMJ case reports, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
A 71-year-old man was admitted to our hospital with right lower abdominal pain. Blood analysis indicated severe inflammation, and abdominal CT revealed a pancreatic head tumour and multiple lung nodules. The level of a tumour marker was high. Pancreatic cancer with multiple lung metastases was suspected; however, because the mass was not detected via endoscopic ultrasonography, it was not biopsied. The serum creatinine level increased rapidly with a urine disorder, and myeloperoxidase-antineutrophil cytoplasmic antibody staining was positive. Severe rapidly progressive glomerulonephritis (RPGN) and microscopic polyangiitis were diagnosed, and high-dose glucocorticoid treatment was started. The patient's high fever returned to normal, and the serum creatinine level declined. Because the RPGN was severe, cyclophosphamide was administrated, and the glucocorticoid was tapered. The pancreatic tumour regressed, the lung nodules disappeared, and the tumour marker level normalised during the treatment. Renal function improved, and maintenance haemodialysis was avoided.
