Methionine Ameliorates Polymyxin-Induced Nephrotoxicity by Attenuating Cellular Oxidative Stress.
Article in Antimicrobial agents and chemotherapy, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 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
Polymyxins are a last line of defense against multidrug-resistant Gram-negative pathogens. Recent pharmacological data show that intravenous polymyxins can cause nephrotoxicity in up to 60% of patients, and the plasma concentrations of polymyxins achieved with the currently recommended dosage regimens are suboptimal in a large proportion of patients. Simply increasing the daily dose of polymyxins is not possible due to nephrotoxicity. This study aimed to examine the protective effect of methionine against polymyxin-induced nephrotoxicity. Methionine (400 mg/kg of body weight), polymyxin B (35 mg/kg), a combination of methionine (100 or 400 mg/kg) and polymyxin B, and saline were administered to mice twice daily over 3.5 days. Kidneys were collected immediately at the end of the experiment for histological examination. The effect of methionine on the pharmacokinetics of polymyxin B was investigated in rats. The attenuation of polymyxin B (0.75 mM)-induced mitochondrial superoxide production by methionine (10.0 mM) was examined in rat kidney (NRK-52E) cells. Histological results revealed that the polymyxin-induced nephrotoxicity in mice was ameliorated by methionine in a dose-dependent manner. The methionine doses were well tolerated in the mice and rats, and the pharmacokinetics of polymyxin B in rats were not affected by methionine. In the group receiving polymyxin B-methionine, the total body clearance of polymyxin B was very similar to that in the group receiving polymyxin B alone (3.71 ± 0.57 versus 3.12 ± 1.66 ml/min/kg,
