How to Optimize Trichoscopy for Evaluation of Scalp Vessels.
Article in Skin appendage disorders, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
introductionTrichoscopy greatly facilitates clinical diagnosis in patients with hair loss and may decrease the necessity for histopathological examination. Structures which may be revealed by trichoscopy include hair shafts, hair follicle openings, the perifollicular epidermis, and cutaneous microvessels. Cutaneous microvessels revealed in trichoscopy may vary in type and number depending on the scalp area, type of the disease, and its activity. Firm direct pressure (diascopy) might result in their blanching, but as of yet, there are no studies on the types of vessels that do or do not blanch on applying pressure.
methodsWe studied interfollicular twisted loops in 16 cases of biopsy-confirmed scalp psoriasis and 37 cases of arborizing vessels in normal subjects and seborrheic dermatitis patients.
resultsWe observed that all arborizing red line vessels blanched on applying pressure. Instead, the vast majority of twisted and simple loops, despite their vascular nature, did not blanch on performing diascopy.
conclusionIn the light of these findings, diascopy of vascular changes in hair loss patients might provide additional clues for a proper diagnosis, especially in differentiating scalp psoriasis, seborrheic dermatitis, and discoid lupus erythematosus.
