Purple Urine Bag Syndrome in the Setting of a Percutaneous Nephrostomy: Case Report and Review of the Literature.
Article in Journal of Brown hospital medicine, 2026. 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
Purple Urine Bag Syndrome (PUBS) is an uncommonly described entity in which purple discoloration of urine can be seen in patients with recurrent urinary tract infection or bacterial colonization. It most commonly affects patients with chronic indwelling foley catheters and those who are chronically debilitated. Reports of PUBS affecting patients with percutaneous nephrostomy tubes are even less common. While the finding is thought to be benign, it is important to recognize, as it can understandably cause concern amongst patients and health care workers alike, and may lead to unnecessary workup and treatment. We thus present the following case and review of this rare phenomenon in a patient with a percutaneous nephrostomy tube.
