A Case of Cast Nephropathy Found as the Cause of Severe Renal Failure.

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
Cast nephropathy is rare kidney disease with slow progression. It is associated with multiple myeloma (MM). In this study, we report a case of cast nephropathy in an 86-year-old woman who was previously independent in her activities of daily living (ADLs). However, she was found to have severe renal impairment after vomiting and a decrease in her ADLs. Blood and urine tests revealed the renal disorder. The patient was immediately treated with hemodiafiltration. IgG, IgA, and IgM levels were decreased by immunoelectrophoresis. A kidney biopsy showed crystals and periodic acid-Schiff stain (PAS)-negative urinary casts in the tubules. Bence Jones protein-lambda type M protein was detected in the urine. The patient was diagnosed with cast nephropathy due to MM. Hemodialysis was continued. The patient's family and the patient did not wish to initiate chemotherapy. The decision was made to follow the patient's progress. In this case, a patient who was originally independent in her ADLs developed severe renal failure with an acute course. This case suggests the importance of differentiating MM based on renal failure, even if the presentation is not typical, as elderly patients may have an atypical presentation of the disease, which can avoid invasive procedures such as renal biopsy.
