Are Preferred Scalp Locations for Alopecia Areata Patches a Clue to Neuronal Etiology?
Article in Skin appendage disorders, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundAlopecia areata (AA) is an autoimmune disease causing hair loss in 2% of the population. Anecdotally, hair specialists report that patches localize to the scalp periphery. Changes in sensory innervation and/or scalp vasculature may play a role in the development and localization of alopecic patches.
objectiveTo evaluate the most common locations of initial alopecic scalp patches. MATERIALS AND
methodsA retrospective chart review, with comprehensive evaluation of clinical photographs, was conducted from July 2016 to June 2018 to include AA patients (
resultsThe most common areas of initial AA patches in both females and males were the occiput (49 vs. 48.5%), parietal (46.9 vs. 21.2%), vertex (26.5 vs. 18.2%), and frontal (24.5 vs. 18.2%) regions; 26.8% of patients present with either alopecia totalis or universalis. LIMITATIONS: This is a single-center study with underrepresentation of minority races.
conclusionAA patches most commonly present on the occiput of the scalp in both female and male patients. Cervical spine nerves C3 and C2 supply sensory innervation and the occipital artery supplies blood to this area.
