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
backgroundBenzoyl peroxide is a peroxide with antibacterial, irritating, keratolytic, comedolytic, and anti-inflammatory properties. When benzoyl peroxide is applied topically, it breaks down and releases oxygen, which kills the germs of Propionibacterium acnes. Benzoyl peroxide's irritating impact causes an increase in epithelial cell turnover, which causes the skin to peel and aids in the healing of comedones. Treatment for acne vulgaris involves the use of benzoyl peroxide.
objectiveThe research is aimed at studying the formulation of Microsponge gel preparation of benzoyl peroxide by using Carbopol 934 as a gelling agent and evaluation of microsponge gel formulation for its physicochemical properties.
methodsMicrosponges of anti-acne agent benzoyl peroxide drug were prepared by quasi-emulsion method, and in-vitro drug release using a suitable membrane model using a simple diffusion cell. RESULTS AND DISCUSSION: Prior to drying, the microsponge was filtered and rinsed using distilled water. Formulation containing benzoyl peroxide and Eudragit RS100 with a ratio of 1:4 showed a high 87.5% drug content and 78.20 % yield. The drug content of the microsponge gel was found to be 84%. Microbiological study on S. aureus was conducted by the cylinder cup method and found good results. The invitro diffusion of microsponge formulations was sustained for 8 hours. The drug release rate for Eudragit RS-100 was reported to be 88.87% after 8 hours based on the polymer: drug ratio (4:1).
conclusionThe quasi-emulsion solvent diffusion method was used to successfully prepare benzoyl peroxide microsponges using Eudragit RS100, Ethyl Cellulose, and HPMC K4M as polymers. The formulations with the highest medication concentration were made with the porous polymer Eudragit RS100.
