Combined micro-needling with topical metformin versus micro-needling with topical placebo in the treatment of melasma: a concurrent split-face study.

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
Melasma is an acquired dysfunction of melanogenesis, that poses a major therapeutic challenge and tends to recur after therapy. Several combination therapies are being tested nowadays for the treatment of melasma, with promising results. Metformin, an anti-diabetic medication, seems to inhibit melanogenesis by different mechanisms. In addition, there has been a long-term improvement in melasma after microneedle therapy. To evaluate the potential therapeutic role of topical metformin combined with micro-needling for the treatment of melasma. Eighteen patients with melasma received treatment in split-face manner, right side with micro-needling and topical metformin, while the left side was treated with micro-needling and topical placebo for four sessions at 2-week intervals. Hemi-mMASI score was used for the final evaluation of results. The variability pattern in Hemi-mMASI score between both sides revealed significant reduction in the right side (micro-needling + metformin), as compared to the left side (micro-needling + placebo) (2.39 ± 1.42 vs 4.72 ± 1.27, p = 0.001). The effectiveness of topical metformin in the management of melasma could be significantly improved by pretreatment with micro-needling as a combined therapy, without any apparent side effects.
