Association between alopecia areata and COVID-19: A systematic review.
Review in JAAD international, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 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
backgroundCOVID-19 may play a role in various immune-related dermatologic conditions. The relationship between COVID-19 and alopecia areata remains unclear.
objectiveTo review the existing literature for clinical studies and reports investigating the association between new-onset alopecia areata or the exacerbation of preexisting alopecia areata following infection with SARS-CoV-2.
methodsA systematic review of the literature was performed using PubMed, Embase, and MEDLINE databases from inception to October 2021. Included articles assessed alopecia areata following infection with SARS-CoV-2.
resultsOf 402 total articles, 9 were identified as meeting the inclusion criteria. Six articles described case reports of 7 patients with new-onset alopecia areata following confirmed infection with SARS-CoV-2, and 3 articles reported on alopecia areata recurrence or exacerbation following SARS-CoV-2 infection in patients with preexisting disease. Studies investigating the exacerbation or recurrence of alopecia areata following infection reported mixed findings. LIMITATIONS: A majority of the included studies were case reports. The heterogeneity of articles precluded data synthesis.
conclusionAlopecia areata may be a dermatologic manifestation of COVID-19, with cases most often appearing 1 to 2 months following infection. Additional research is necessary to better elucidate the relationship and draw conclusions.
