Infectious bronchitis virus Mass-type (GI-1) and QX-like (GI-19) genotyping and vaccine differentiation using SYBR green RT-qPCR paired with melting curve analysis.
Article in Journal of virological methods, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Infectious Bronchitis Virus (IBV) is a highly contagious virus of chicken, causing huge economic losses in the poultry industry. Many genotypes circulate in a given area, and optimal protection relies on vaccination with live attenuated vaccines of the same genotype. As these live vaccines are derived from field viruses and circulate, understanding the prevalence of different IBV genotypes in any area is complex. In a recent study, the genome comparison of an IBV QX vaccine and its progenitor field strain led to the identification of vaccine markers. Here we developed a simplex SYBRgreen RT-qPCR assay for differentiation between QX-like field and vaccine strains and a multiplex SYBRgreen RT-qPCR assay for IBV genotyping with melting curve analysis, as each virus produced distinct and reliable melting peaks. Both the simplex and the multiplex assays showed excellent efficiency, sensitivity and specificity representing a low cost diagnostic tool for IBV genotyping and vaccine differentiation.
