Alternaria koreana sp. nov., a new pathogen isolated from leaf spot of ovate-leaf Atractylodes in South Korea.
Article in Molecular biology reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
backgroundA new species within the genus Alternaria was isolated from the leaf spot of Atractylodes ovata in the Mungyeong and Hwabuk-myeon districts of the Gyeongbuk province of Korea. The leaves showed disease symptoms such as circular or irregular leaf spots and brown to dark brown with gray spots at the center. The leaves also showed that concentric rings were surrounded with yellow halos. METHODS AND
resultsPhylogenetic analysis was conducted using the sequence dataset of the internal transcribed spacer region and part of the glyceraldehyde-3-phosphate dehydrogenase. The RNA polymerase II second largest subunit, endopolygalacturonase, Alternaria major allergen gene, anonymous gene region, and translation elongation factor 1-alpha genes were used as well. Results showed that present fungal isolates were distinct from other species of the sect. Alternaria. Morphologically, the present isolates also differed from other members of the sect. Alternaria in their production of solitary conidia or conidial chains (two units) and conidial body features. Similarly, it exhibited moderate pathogenicity in the host plant.
conclusionsThis study described and illustrated A. koreana as a new species and the causal agent of the leaf-spot disease on A. ovata in Korea.
