1 · What the graph read from it

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.

2 · The registry

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

Drug-induced urine discoloration, although usually benign, can still raise concern in healthcare facilities. This case report presents the second case of purple urine discoloration associated with cefiderocol in a 64-year-old male admitted to the intensive care unit for ventilator-associated pneumonia. The patient required broad-spectrum antibiotic treatment with vancomycin, cefiderocol, amikacin, and micafungin. On the fourth day after initiating antibiotics, the presence of purplish urine in the foley bag was noted. Urinalysis showed 11-25 red blood cells/hpf, but cultures ruled out urinary tract infection. Further laboratory workup did not reveal any evidence of hemolysis or rhabdomyolysis. Cultures from the endotracheal aspirate grew multidrug-resistant Pseudomonas. Cefiderocol and amikacin were continued to complete a seven-day course. Two days after completion of the cefiderocol course, the urine discoloration cleared up, providing strong evidence that cefiderocol was the cause of the discoloration.
