Reversible alopecia areata: a little known side effect of leflunomide.
Article in Clinical rheumatology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
Leflunomide is a disease-modifying anti-rheumatic drug (DMARD) used in the management of rheumatoid arthritis (RA) and psoriatic arthritis. Commonly reported adverse effects include diarrhea, nausea, hepatotoxicity, hypertension, and transient global hair loss; however, additional side effects may be associated with the medication not reported in the monograph. We describe a rare case of reversible alopecia areata (AA) associated with the use of leflunomide and provide a literature review of three published similar cases. We use the Naranjo adverse drug reaction score to show the AA in our case is a "probable" side effect of leflunomide. Currently, AA is not listed as an adverse effect in the leflunomide product monograph. However, it would appear that based on our case and the three other reported cases, the likelihood of AA being an adverse effect of leflunomide is at least possible to probable.
