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
purposeMeasurement of skin absorption of ions requires specific experimental protocols regarding the use of pig skin as a model, the viability of excised skin in water medium over 24 h, the presence of endogenous ions, and evaluation of the contributions of facilitated transport through ion channels and ion transporters.
methodAbsorption experiments of halide anions F(-), Cl(-), Br(-) and I(-) in excised skin were performed in Franz diffusion cells. Experiments were performed on human and porcine skin under various conditions so as to define and validate experimental protocols.
resultsThe distributions of endogenous ions and the absorption kinetics of halide ions were similar in both porcine and human skin models. Fresh skin kept its viability over 24 h in salt-free water, allowing experiments following OECD guidelines. Permeation increased in the order F(-) < Cl(-) < Br(-) < I(-) for all receptor media and skin samples. Absorption was larger in fresh skin due to the transport through chloride channels or exchangers.
conclusionSkin absorption experiments of ions in Franz cells rely on working with fresh excised skin (human or porcine) and pure water as receptor fluid. Experiments with chloride blockers or frozen/thawed skin allow discriminating passive diffusion and facilitated transport.
