Characterization of Newcastle disease virus in broiler flocks with respiratory symptoms in some provinces of Iran.
Article in Molecular biology reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundNewcastle disease, is one of the most important diseases of the poultry industry, has many economic losses. The aim of this study was to isolate and determine the molecular identity of Newcastle disease virus in 40 broiler flocks with respiratory symptoms in four provinces of Iran. METHODS AND
resultsSamples of farms with respiratory symptoms were collected from different regions of Isfahan, East Azerbaijan, Golestan, and Khuzestan provinces and inoculated into 9-day-old embryonated chicken eggs. The Reverse-transcription polymerase chain reaction (RT-PCR) was performed to detect the Newcastle disease virus in allantoic fluid. Of the 40 flocks, the virus was isolated and identified in 16 flocks. The PCR products of 16 isolates were sequenced, and a phylogenetic tree was drawn. Accordingly, six isolates were in genotype II and ten isolates were in subgenotype VII.1.1 (VIId) of class II.
conclusionBoth genotypes were present in all four provinces. The isolates of Khuzestan province showed the greatest diversity compared to the other three provinces. The similarity of isolates belonging to genotype II in this study was observed with Pakistan, China, and Nigeria, and other isolates were similar to previous isolates in Iran. Also, the highest amino acid sequence in the F-protein cleavage site was 112RRQKR/F117 for VII.1.1 (VIId) genotype isolates and 112GRQGR/L117 for II genotype isolates.
