Purple Urine Bag Syndrome: Antibiotic Treatment or Not?
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Purple urine bag syndrome (PUBS) is a relatively rare phenomenon characterized by purple discoloration of the urine, catheter, and collection bag in individuals with indwelling catheters often colonized by specific bacteria. Although typically asymptomatic, it requires appropriate diagnostic evaluation and, in some cases, targeted treatment. We present a case study of an 81-year-old male with an indwelling urinary catheter who developed an uncomplicated, self-limiting case of purple urine bag syndrome. The patient exhibited the characteristic purple discoloration of the catheter tubing and collection bag, without accompanying systemic symptoms such as fever, dysuria, flank pain, or altered mental status. This case underscores the importance of recognizing PUBS as a benign condition in many instances, to avoid unnecessary diagnostic testing or antibiotic therapy, while still ensuring appropriate clinical evaluation to rule out potential underlying infections or contributing risk factors.
