1 · What the graph read from it

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.

2 · The registry

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

The stratum corneum (SC), the outermost layer of skin, represents the primary barrier to molecules penetrating the skin. Menthol is widely used in clinical medicine as a penetration enhancer due to its high efficiency and relative safety. In this study, molecular dynamics simulations have been performed to investigate the effect of menthol molecules on the structural and permeability of both single component and ternary mixed bilayers. The lipid matrix is modeled as pure ceramide (CER2) or as a 2:2:1 mixture of CER2, cholesterol (CHOL), and free fatty acid (FFA). The effect of menthol on the SC bilayer was investigated at various concentrations of menthol. For both models, the area per lipid decreases and the membrane thickness increases with increased menthol concentration, which may be due to the fact that menthol molecules penetrate into the bilayer and aggregate at the bilayer center. As for ternary mixed bilayer at high concentration, the lipids rearranged, and one more layer formed inside the former two leaflets. Our simulation results are consistent with the experimental evidence that high concentrations of menthol fluidize the SC lipids and enhance permeability. The penetration enhancement of menthol may take place through direct interactions with lipids rather than by forming water pores. Graphical abstract The effect of menthol on the structural and permeability of skin lipids was investigated using a molecular dynamics simulation method. Increased menthol concentration makes the area per lipid decrease and the membrane thickness increase. Our results show that the penetration enhancement of menthol may take place through direct interactions with lipids.
