Not all that is red is blood: a curious case of chromaturia.
Article in Clinical case reports, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Hydroxocobalamin causes reddish discoloration of the urine, mimicking hematuria. Clinicians should be aware of this common side effect of the rarely used drug to prevent unnecessary consultations and work-up. Additional benign causes of red urine include foods such as beets, rhubarb, and medications such as rifampin, phenazopyridine.
