Renal infiltration of peripheral T-cell lymphoma, not otherwise specified, mimicking drug-induced acute interstitial nephritis.
Article in CEN case reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Renal invasion of T-cell lymphoma does not usually occur. The renal infiltration of peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS), is rare. Therefore, the detailed pathology, clinical features, and effective therapy of this type of extranodal disease remain uncovered. Here, we report the rare case of acute kidney injury (AKI) caused by the renal infiltration of PTCL-NOS with no evidence of lymphadenopathy and extranodal lesions, except for the kidney. We mistakenly diagnosed our patient with drug-induced acute interstitial nephritis (AIN) at first, because his clinical features were similar to those of drug-induced AIN; however, we reached the correct diagnosis by detecting atypical T-cells in his urine. After the introduction of cyclophosphamide, doxorubicin, vincristine, and prednisone therapy his general condition improved rapidly. When suspecting drug-induced AIN as the cause of AKI, PTCL-NOS should also be recognized as one of the causes, and urine cytology may be useful to noninvasively distinguish between the two diseases.
