Evaluation the efficacy of microneedling with topical metformin solution compared with microneedling with topical vitamin C solution in treatment of melasma.
Article in Archives of dermatological research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07345507 (Comparison of Efficacy of Metformin Gel 30% vs Triple Combination Cream), which is not on this map. Cited by 2 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

Abstract
Several treatment modalities have been used for the treatment of melasma. Topical metformin is an anti-diabetic drug, which has melanopenic action. Vitamin C acts on melanin by inhibiting the tyrosinase enzyme, thus inhibiting melanogenesis. To compare the efficacy and safety of microneedling combined with topical metformin solution versus microneedling combined with topical vitamin C in the treatment of melasma. A spitted-face interventional comparative on 30 female patients suffering from melasma. The right side of the face was treated with microneedling and topical metformin, while the left side was treated with microneedling and topical vitamin C solution. Hemi-MASI score decreased significantly after treatment from before treatment in both groups P-value < 0.001. The percentage of improvement of Hemi-MASI score metformin group was 48.29%, While with vitamin C group was 37.19%. There was a significant improvement in dermoscopic findings in microneedling with topical metformin than with topical vitamin C group. Microneedling with topical metformin or topical vitamin C solution can be an effective and safe therapeutic option for treating melasma with no significant side effects.
