Bismuth Porphyrin Antagonizes Cisplatin-Induced Nephrotoxicity via Unexpected Metallothionein-Independent Mechanisms.
Article in iScience, 2020. 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
Cisplatin (CDDP) has been a highly successful anticancer drug in cancer therapy; however, its further application suffers severe nephrotoxicity. Herein, we identify bismuth tetraphenylporphyrinate [Bi(TPP)] as a potent protective agent against CDDP-induced nephrotoxicity. Bi(TPP) attenuates CDDP-induced acute kidney injury and prevents the death of mice exposed to a lethal dose of CDDP. The protective potency of bismuth porphyrin complexes could be optimized by varying lipophilic TPP ligands with ideal ClogP values of 8-14. Unexpectedly, Bi(TPP) exhibited a protective role via metallothionein-independent pathways, i.e., maintenance of redox homeostasis and energy supplement, elimination of accumulated platinum in the kidney, and inactivation of caspases cascade in apoptotic pathway. Significantly, Bi(TPP) does not compromise the antitumor activity of CDDP in the orthotopic tumor xenograft mouse model. These findings suggest that Bi(TPP) could be incorporated into current CDDP-based cancer therapy as a nephroprotective agent.
