Trichoscopic Features of Lichen Planopilaris versus Frontal Fibrosing Alopecia: A Systematic Review.
Review in Dermatology practical & conceptual, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
introductionLichen planopilaris (LPP) and frontal fibrosing alopecia (FFA) are primary scarring alopecias that few authors consider the same entity, and some consider them different. Only a few reviews focus on trichoscopic findings in delineating these two alopecias.
objectiveWe describe and summarize the trichoscopic features of both conditions.
methodsWe performed an extensive literature search using the PubMed and Google Scholar databases. The Chi-square test was applied to compare the trichoscopic features in LPP and FFA. P-values less than 0.05 were considered statistically significant.
resultsOut of 60 articles, 33 (16 LPP, 17 FFA) were considered for quantitative analysis due to availability in English literature with full text. We found that peripilar cylindrical casts and perifollicular erythema with arborizing vessels were predominant features suggesting early LPP. In contrast, yellow dots, perifollicular erythema, and scattered pigmentation suggested active FFA. Shiny-white area was seen in both groups in the inactive stages. The target arrangement of blue-grey dots, milky-red areas, and irregularly arranged white fibrotic dots were seen in late LPP, and black dots, lonely hairs, and loss of vellus hairs were detected in the later stages of FFA. Features such as blue-grey structureless areas, blue-white veil, and variability in morphologies of hair shafts were not significantly different between the two groups.
conclusionThis article provides a comprehensive literature review on the trichoscopic features of LPP and FFA, including comparing the similarities, differences, and peculiarities of both conditions.
