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
backgroundChemotherapy-induced alopecia (CIA) significantly impacts patients' emotional and psychological well-being and treatment regimen. Phenylephrine, a topical vasoconstrictor, can potentially reduce hair loss by limiting chemotherapy drug delivery to hair follicles. However, effective delivery of Phenylephrine through the skin remains challenging. This study investigates lipid vesicles as delivery vehicles to enhance Phenylephrine's skin permeation and sustained release due to their biocompatibility and encapsulation capabilities.
objectiveThis study aimed to formulate and compare different lipid vesicles of Phenylephrine HCl for enhanced permeation through the skin for deep dermal delivery with sustained release of the drug so as to achieve local vasoconstriction.
methodsPhenylephrine-loaded ethosomes, invasomes, and transfersomes were prepared and characterized for particle size (PS), polydispersity index (PDI), and entrapment efficiency (EE %). These lipid vesicles were incorporated into hydrogels to facilitate sustained drug release to deep dermal layers where they could target local vasculature and cause vasoconstriction. The prepared vesicular gels were evaluated for various permeation parameters.
resultsThe entrapment efficiencies of the developed vesicles ranged from 49.51 ± 3.25% to 69.09 ± 2.32%, with vesicle sizes ranging from 162.5 ± 5.21 nm to 321.32 ± 3.75 nm. Statistical analysis revealed significantly higher flux values (Jss, μg/cm
conclusionThe results demonstrate that ethosomal and invasomal formulations were efficient in delivering the drug to deep dermal layers of skin in a sustained manner. These findings suggest that these Lipidic vesicles would be able to target the local vasoconstrictor to vasculature, causing reduced hair loss by limiting chemotherapy drug delivery to hair follicles and managing chemotherapy-induced alopecia.
