Acaricidal activity of usnic acid and sodium usnic acid against Psoroptes cuniculi in vitro.
Article in Parasitology research, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Usnic acid, a major active compound in lichens, was first isolated in 1884. Since then, usnic acid and its sodium salt (sodium usnic acid) have been used in medicine, perfumery, cosmetics, and other industries due to its extensive biological activities. However, its acaricidal activity has not been studied. In this paper, we investigated the acaricidal activity of usnic acid and sodium usnic acid against Psoroptes cuniculi in vitro. After evaluating the acaricidal activity and toxicity of usnic acid and sodium usnic acid in vitro, the results showed that at doses of 250, 125, and 62.5 mg/ml, usnic acid and sodium usnic acid can kill mites with 91.67, 85.00, and 55.00% and 100, 100, and 60.00% mortality after treatment 24 h. The LT50 values were 4.208, 8.249, and 16.950 h and 3.712, 7.339, and 15.773 h for usnic acid and sodium usnic acid, respectively. Sodium usnic acid has a higher acaricidal activity than usnic acid, which may be related to the difference in their structures.
