A Split Face Study to Compare the Efficacy of Platelet-Rich Plasma Combined with Microneedling Versus Microneedling Alone for Treatment of Acne Scars.
Article in Indian dermatology online journal, 2026. 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
backgroundMicroneedling is one of the cost-efficient and safe procedures for treatment of atrophic scars. Previous studies have shown variable results regarding the increased efficacy of platelet-rich plasma (PRP) when combined with microneedling.
objectivesThe aim of this split-face study was to compare the efficacy of PRP combined with microneedling versus microneedling alone in acne scars in type 3-6 skin in South Indian patients. The primary objective was to compare the mean reduction in acne scar using Goodman Baron quantitative scale on the side of the face treated with PRP and microneedling, with the side of the face treated with microneedling alone. PATIENTS AND
methodsA total of 64 patients were recruited, and three sessions of microneedling with PRP on the right side and microneedling on the left side were done with an interval of 4 weeks between the sittings. Results were evaluated after 1 month of the last sitting using Goodman and Baron's score and physician and patient satisfaction score.
resultsThere was significant improvement in atrophic acne scars on both sides of the face before and after treatment. While comparing efficacy between sides, the side treated additionally with PRP had significantly more improvement than the side treated with microneedling alone. LIMITATIONS: The trial was non-randomized, and complete blinding was not done. The study had a shorter follow -up interval. We did not analyze results based on the site of scar.
conclusionPRP combined with microneedling is more effective than microneedling alone for the treatment of atrophic acne scars. Larger studies with longer follow-up are needed to confirm this result.
