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
Using tamsulosin (TAL) as a model drug, the aim of this study was to investigate and compare the percutaneous permeation behavior of two menthol derivatives, 2-isopropyl-5-methylcyclohexyl heptanoate (M-HEP) and 2-isopropyl-5-methylcyclohexyl decanoate (M-DEC). In vitro transdermal permeation study was carried out using porcine skin. The residual amount of enhancers in the skin after permeation experiment was determined by gas chromatographic (GC) method. The penetration depths of fluorescein were visualized by two-photon confocal laser scanning microscopy (2P-LSM) after the skin being treated with different enhancers. Furthermore, changes in the stretching frequency of functional group of ceramide were investigated by using attenuated total reflectance Fourier transform infrared (ATR-FTIR) technique. After M-HEP addition, the cumulative amount of TAL permeated in 8 h (Q8) reached 20.57±0.54 μg/cm2 and the depth of fluorescein was 40 μm; the CH2 of ceramide symmetric stretching frequency was 4 cm−1 blue shifted. However, M-DEC has an opposite effect on TAL permeation compared with that of M-HEP. TAL is a crucial factor affecting permeation procedure, and microenvironment of lipid region determines promotion capability of the enhancers.
