Article in Current drug delivery, 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
introductionMethicillin-Resistant Staphylococcus Aureus (MRSA) is a major cause of purulent Skin and Soft-Tissue Infections (SSTIs), posing significant global health and economic challenges. This study aims to optimize a drug delivery system, specifically Tigecycline-loaded transfersomes, to address the limitations of current treatments, including bacterial resistance, systemic side effects, and poor drug penetration, thereby offering a safer and more effective alternative for MRSArelated SSTIs.
methodsA novel Tigecycline transfersomal formulation was developed using the thin film hydration method. The study investigated the effects of varying drug-to-lipid ratios, lipid-to-edge activator ratios, and different hydration media on the characteristics of the Tigecycline-loaded transfersomes. The formulation's morphology, release profile, and antibacterial activity against clinical MRSA strains were also evaluated.
resultsThe Tigecycline-loaded transfersomes were successfully prepared with particle sizes ranging from 92.3 to 290.8 nm, zeta potential values from -16.22 to -48.7 mV, and encapsulation efficiencies ranging from 54.8% to 84.39%. The formulation prepared using distilled water as the hydration medium, a lipid-to-edge activator ratio of 80:20, and a drug-to-lipid ratio of 3:8 was selected for further assessment due to its optimal characteristics. The selected transfersomes were spherical with an average diameter of 131 nm. The formulation exhibited a controlled drug release profile and demonstrated a twofold increase in antibacterial activity against MRSA compared to non-liposomal Tigecycline. DISCUSSION: The results highlighted the significant role of formulation parameters in tailoring transferosomal characteristics and enhancing therapeutic performance. The study builds on existing research by introducing Tigecycline-a broad-spectrum antibiotic-into transfersomal systems for the first time. However, further in vivo validation is necessary.
conclusionTigecycline-loaded transfersomes demonstrated improved drug delivery and antibacterial efficacy against MRSA. This novel formulation shows promise as an effective topical therapy for antibiotic-resistant SSTIs.
