A variable-pulse copper vapor laser at 578 nm application for the treatment of facial resistant Port wine stains: case report.
Article in Lasers in medical science, 2025. 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
Port wine stain (PWS) is presented as a vascular anomaly, light pink to purple in color with various grades of hypertrophy. Facial unilateral upper eyelid and hypertrophic PWS have been reported to be most resistant to pulsed dye laser treatment due to larger vessel diameter and vessel depth.Therefore, it highlights the need for testing new laser modalities for the management of resistant PWS.56-years-old adult II Fitzpatrick phototype female patient, presented with a resistant hypertrophic PWS on the forehead and upper eyelid on the left is presented. Patient was treated with dual-wavelength copper vapor laser (CVL) radiation at 578 nm wavelength. The average power was 0.7-0.8 W with an exposure time of 0.08 -0.2 s.The spot size was1 mm.Patient showed about 75 % lightning of PWS after 2 copper vapor laser treatments. No recurrences were observed during the follow-up period up to 7 years.The variable-pulse copper vapor laser radiation at 578 nm proved to be a minimally invasive, safe and effective treatment for resistant and hypertrophic PWS with a good cosmetic outcome, without side effects (erythema, scarring, depigmentation).
