The antirheumatic drug sulfasalazine ameliorates acute renal failure (ARF) induced by polymyxin B.
Article in The Journal of antibiotics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Polymyxin B (PMB) is a polypeptide antibiotic active against multidrug-resistant bacteria, including multidrug-resistant Pseudomonas aeruginosa (MDRP). However, PMB frequently initiates serious acute renal failure (ARF). Our recent study demonstrated that PMB-induced ARF is triggered by inflammatory responses mediated by activation of the NOD-like receptors protein 3 (NLRP3) inflammasome. Here, we provide evidence that sulfasalazine (SSZ), a clinically-used disease-modifying antirheumatic drug (DMARD), can ameliorate PMB-induced ARF in a mouse model of ARF. Since SSZ strongly inhibited the NLRP3 inflammasome activation induced by PMB in macrophages, as previously demonstrated, the amelioration of PMB-induced ARF appears to be brought about by the inhibition of the NLRP3 inflammasome activation. Thus, if SSZ could be effectively utilized in clinical practice, it may be possible to overcome ARF caused by polypeptide antibiotics.
