Isolation and characterization of eleven novel microsatellite markers for fine-scale population genetic analyses of Gammarus pulex (Crustacea: Amphipoda).
Article in Molecular biology reports, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The freshwater amphipod species Gammarus pulex (Linnaeus, 1758) is widespread across Europe and Asia and is able to live in a broad range of environmental conditions. Yet, it is of great interest to which degree it is able to tolerate and adapt to the current rapid anthropogenic environmental changes affecting its habitat, such as pollution, changes in river morphology, and invasions of alien gammarid species. Microsatellite primers for genetic population studies with G. pulex have been developed but due to the existence of several genetically different lineages within the species, the application of these primers is not always successful. In order to investigate the impacts of anthropogenic environmental changes on the spatio-genetic patterns of G. pulex lineage E in streams in the Saale river catchment in Germany, we designed eleven novel polymorphic microsatellites for this lineage using a high-throughput sequencing approach. These microsatellites enabled highly specific characterization of three closely related populations. The results show genetically distinct populations reflected by both a principal coordinates analysis and an analysis of molecular variance. Several of the newly designed microsatellite primers also enabled successful cross-amplification of the respective microsatellites in specimens of G. pulex lineage C, while only two microsatellites were amplified successfully and showed polymorphisms for all of the analyzed specimens of G. fossarum Koch, 1836. The microsatellites identified here are suitable for future assessments of micro-evolutionary dynamics of G. pulex from central Germany.
