Pattern of Facial Dyschromias: A Clinical and Dermoscopic Study from a Tertiary Healthcare Center in South India.
Article in Indian dermatology online journal, 2026. 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
backgroundFacial dyschromias (FD) are common among individuals with skin of color. At present, information on the pattern and dermoscopic features of various FD is scarce from South India.
objectiveTo describe the clinical and dermoscopic features of FD in patients presenting to a tertiary healthcare center in South India. PATIENTS AND
methodsClinical and dermoscopic examination was performed in 274 patients presenting with FD in the outpatient department of a tertiary healthcare center in South India.
resultsDisorders of facial hyperpigmentation (90.87%) were more commonly encountered than facial hypopigmentation (7.66%); four patients presented with both hyperpigmentation and hypopigmentation (1.46%). Females (76.27%) were more commonly affected than males (23.72%), and most of the patients belonged to the young to middle-aged groups. The common causes of facial hyperpigmentation include melasma, lichen planus pigmentosus, facial acanthosis nigricans, maturational dyschromia, and post-inflammatory hyperpigmentation. The common causes of facial hypopigmentation include tinea versicolor, seborrheic dermatitis, vitiligo, salt and pepper pigmentation, and nevus depigmentosus. Each of these conditions had distinct dermoscopic features, which aided in the diagnosis. LIMITATIONS: Histopathological examination was done in a limited number of cases, being a cross-sectional study, and no follow-up was conducted to observe the evolution of facial pigmentation.
conclusionNearly 90% of FD are hyperpigmentary in nature. The common causes of facial hyperpigmentation include melasma, lichen planus pigmentosus, facial acanthosis nigricans, maturational dyschromia, and post-inflammatory hyperpigmentation. In contrast, tinea versicolor, seborrheic dermatitis, and vitiligo are three common causes of hypopigmentation of the face.
