Paradoxical Nonscarring Alopecia Following Mesotherapy with Dutasteride: A Case Series.
Article in International journal of trichology. 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
Background: Androgenetic alopecia (AGA) is a disease of polygenic etiology. Androgens play a vital role in the development of patterned hair loss. Dutasteride is an anti-androgen that acts by competitively inhibiting both type 1 and type 2 isoenzymes of 5α reductase. The intradermal deposition of dutasteride has the advantage of negligible systemic absorption. Although dutasteride mesotherapy has not been approved by the Food and Drug Administration, it has been used off-label in the treatment of AGA. Here, we report 4 case series of nonscarring alopecia that developed following a single session of mesotherapy injection. Materials and Methods: A total of 15 cases with patterned hair loss were enrolled (13 males and 2 females). The grade of patterned hair loss was between Norwood Hamilton grade 3-6, and in Ludwig pattern between 2 and 3. Once a month intradermal injection of dutasteride mesotherapy was administered in all cases. To standardize the drug administration and for uniform delivery of the drug, 1 cm Results: Mean age of 31.53. The most common adverse effect noted was noncicatricial alopecia was noted in four cases, (3 males and 1 female), followed by pain, itching 1 case each, respectively. The grade of alopecia was AGA grade 5-6, 1 male with Ludwig grade 2 pattern of hair loss and a female with Ludwig grade 2. They developed patchy alopecia involving the mesotherapy site following a single session of dutasteride mesotherapy. Conclusion: There is a need for stringent monitoring of manufacturing guidelines of mesotherapeutic cocktails by governing bodies. It should primarily address the optimal concertation of the active ingredients and preservative usage to avoid untoward side effects. The benzyl alcohol and polysiloxane in the cocktail could be the key players having cytotoxic effects, contributing to the development of alopecia. The knowledge of potential adverse effects caused by a drug should always be in the mind of the treating physician.
