Iatrogenic tattoos after acupuncture: successful outcome after treatment with QS Ruby Laser: A case report and review of literature.
Article in Laser therapy, 2019. 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
BACKGROUND AND
aimsAcupuncture has become a substantial part of medical practice in Switzerland. So far, only few cases of accidental tattoo after acupuncture have been reported, which were all caused by acupuncture needles that had been left in the skin and led to local argyrosis. CASE: We report the case of a 31-year-old female who developed gray-brown macules after acupuncture. Over 5 months, she had received acupuncture on the same spots one to two times per week and the macules had gradually become darker and had increased in size. The needles used were disposable, contained nickel and were not left in the skin for over 30 minutes. The patient was of Fitzpatrick skin phototype II and showed several grayish-brown macules with an average diameter of around 5mm in the region of glabella, nucha and dorsum pedis. We treated the lesions with a quality-switched ruby laser (694 nm) with a fluence between 3 and 5.5 J/cm
conclusionIn synopsis with the anamnesis, the clinical aspect and the therapeutic course, we interpreted the hyperpigmentary spots as a combination of iatrogenic tattooing with nickel and deposition of hemosiderin as well as melanin due to repeated mechanical manipulation and UV exposure of the skin. Furthermore, we hereby show the validity of the quality-switched ruby laser in the removal of accidental hyperpigmentation in skin phototype II.
