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

Litchi (Litchi chinensis Sonn., L. chinensis), a type of tree growing in most areas of southern China, produces an edible fruit that is also a source of traditional medicine. Genetic identification of litchi species or cultivars using molecular markers is very important. In this study, a total of six litchi samples from Fujian, Hainan, Guangdong, Guangxi and Sichuan province, as well as one wild Dimocarpus confinis (D. confinis) sample from Guangxi province were collected for genetic analysis. The cluster dendrograms were constructed for genetic analysis on the basis of DNA amplification results by RAPD and ISSR. The improved RAPD amplified DNA with consistent and clear banding patterns. A total of 176 bands were found, indicating a 72.7 % polymorphism in L. chinensis DNA samples. Significant genetic distances were found among the different species or cultivars, with an index of similarity coefficient ranging from 0.59 to 0.87. Similar to RAPD results, ISSR analysis of the L. chinensis DNA samples showed a range of 0.70-0.93 similarity coefficients. The genetic distance between Hainan sample and Sichuan samples was the farthest, which is consistent with their geographic distance. Furthermore, the index of similarity coefficient between D. confinis and L. chinensis was 0.35-0.41 by RAPD and 0.38-0.48 by ISSR, indicating that these two species have significant genetic difference. This study reveals the high level of genetic differences between different litchi species or cultivars, and confirms the significance of the improved RAPD method in genetic characterization of organisms. Taken together, the improved RAPD combined with ISSR analysis can be used frequently for the genetic diversity, germplasm resources preservation, molecular-assisted breeding, and genetic characterization of various organisms.
