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 uncommon but notable clinical phenomenon primarily observed in patients with long-term indwelling catheters. This syndrome is characterized by a striking purple discoloration of the urine collection bag, often indicative of an underlying urinary tract infection (UTI) and associated metabolic processes. PUBS occurs due to the breakdown of indoxyl sulfate, a tryptophan metabolite, by specific bacteria present in the urinary tract. In this report, we present the case of a 73-year-old female with a chronic Foley's catheter, later developed PUBS, accompanied by symptoms of lower abdominal pain, fever, and reduced urine output.
