Efficacy of Botulinum Toxin A for the Management of Melasma: A Split-Face, Randomized Control Study.
Trial report in Journal of cosmetic dermatology, 2025. 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
backgroundMelasma management remains challenging due to its multifactorial nature pathogenesis and recurrent nature. Previous studies showed positive effects of botulinum toxin A (BoNT-A) for treating and preventing ultraviolet-induced hyperpigmentation.
objectiveTo evaluate the effectiveness of adjunctive incoBoNT-A injection combined with triple combination cream (TCC, 4% hydroquinone, 0.05% tretinoin, and 0.01% fluocinolone acetonide) for treating and preventing melasma recurrence compared to topical therapy alone.
methodsA split-face study was conducted in 30 female patients with melasma. One side of the face was randomly applied TCC to the melasma-affected areas for 12 weeks (monotherapy), while the contralateral side received TCC and intradermal incoBoNT-A at baseline and week 12 (combination therapy side). Evaluations were performed at baseline and 2, 4, 8, 12, 16, 20, and 24 weeks. Clinical improvement and melanin index were assessed using the MASI score on the malar area (MASI
resultsTwenty-eight subjects completed the study. The combination therapy side showed significant MASI
conclusionIntradermal incoBoNT-A injection combined with TCC demonstrated superior efficacy in melasma treatment and recurrence prevention compared to TCC monotherapy.
