Species composition and relative abundance of the genus Culicoides (Diptera: Ceratopogonidae) in Romania.
Article in Parasites & vectors, 2020. 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
backgroundCulicoides biting midges are vectors involved in the biological transmission cycle of important animal diseases such as bluetongue and African horse sickness. In Romania, the first outbreaks of bluetongue were reported in 2014, leading to increased activities within the existing entomological surveillance network. The main goals of the surveillance activities were the establishment of the vector free period in relation to animal trade and the identification of Culicoides species involved in the transmission of the pathogen. This study was conducted on the composition and relative abundance of the species belonging to the genus Culicoides (Diptera: Ceratopogonidae) in certain regions of Romania and provided the opportunity to update the existing checklist of Culicoides species of this country.
methodsThe study was conducted in 33 of the 42 administrative units (counties), including a total of 659 catches, in 102 locations. The collections were carried out with UV blacklight suction traps (OVI type). The collected insects were preserved in 70% ethanol. Morphological insect identification was carried out using a stereomicroscope, according to established identification keys. In ten localities the relative abundance of the cryptic species of the Obsoletus complex was determined by multiplex PCR assay based on the ITS2 segment. The identification of the Culicoides chiopterus (Meigen) species by morphological examination was confirmed by PCR assay based on the ITS1 segment.
resultsEleven species were identified using morphological and PCR tools. The rest of the individuals were separated into five taxa. The species of the Obsoletus complex (grouping Culicoides obsoletus (Meigen) and Culicoides scoticus Downes & Kettle) were the most abundant, accounting for 59% of the total number of captured Culicoides spp. Three of the identified species are mentioned, according to our knowledge, for the first time in Romania: Culicoides newsteadi Austen, Culicoides flavipulicaris Dzhafarov and Culicoides bysta Sarvašová, Kočisová, Candolfi & Mathieu.
conclusionsOur study demonstrates that the Culicoides species most commonly cited as being involved in the transmission of arboviruses in Europe (i.e. bluetongue and Schmallenberg viruses) make up a high proportion of adult Culicoides trapped in Romania.
