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

purposeMany topically applied drugs contain esters that are hydrolyzed in the skin. Minipigs have emerged as potential models of human dermatology and, in some aspects, may be superior to commonly used rat skin. The aims of this study were to evaluate the suitability of minipig and rat skin as in vitro models of human epidermal esterase activity.

methodsNaphthyl acetate and para-nitrophenyl acetate were tested as prototypical substrates of carboxylesterases from skin, plasma, and liver. Reaction products were monitored by high-performance liquid chromatography/ultraviolet analysis.

resultsHydrolysis efficiency in skin was higher than plasma, but lower than liver. The esterase efficiency of rat skin microsomes (580-1100 min(-1) mg(-1)) was two to three orders of magnitude higher than human (1.3-4.2 min(-1) mg(-1)) and minipig microsomes (1.2-4.2 min(-1) mg(-1)). Rat skin cytosol (80-100 min(-1) mg(-1)) was 2- to 10-fold more efficient than human (2.4-67 min(-1) mg(-1)) or minipig cytosol (18-61 min(-1) mg(-1)). Most importantly, human skin fractions displayed kinetics of hydrolysis very similar to minipig skin.

conclusionsThese studies show minipig skin as an appropriate, potentially valuable model for human epidermal ester metabolism and support the use of minipig skin in preclinical development of topically applied compounds.
