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

The genus Begomovirus (family Geminiviridae) includes plant viruses that have a negative impact on the production of several economically important crops worldwide. Begomoviruses infect a wide range of non-cultivated plants, which may serve as alternative hosts or inoculum sources for epidemics in crops. In this study, we evaluated the genetic variability and population structure of Macroptilium yellow vein virus (MacYVV; Begomovirus macroptilivenae), associated with non-cultivated Macroptilium spp. in the state of Alagoas (AL), northeastern Brazil. Complete DNA-A sequences (n = 29) were obtained from symptomatic plants collected in different municipalities of AL during 2019 and 2020. Pairwise sequence comparisons indicated a low degree of genetic variability, with 93.9-100% identity to 18 previously characterized sequences. To better understand the population structuring of MacYVV in AL, the complete DNA-A data set (n = 47) was analyzed. Although the DAPC and STRUCTURE approaches yielded slightly divergent numbers of putative MacYVV subpopulations, the results are consistent with the phylogenetic relationships among MacYVV isolates, where five well-supported subgroups correlated with geographic location were observed. The low variability of the MacYVV population could be related to the small number of recombination events detected and be reflective of a long-term virus-host relationship in which the virus is very well adapted to the host.
