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

Manipulation of the coronavirus genome to accommodate and express foreign genes is an attractive approach for gene delivery and vaccine development. By using an infectious cloning system developed recently for the avian coronavirus infectious bronchitis virus (IBV), the enhanced green fluorescent protein (EGFP) gene, the firefly luciferase gene and several host and viral genes (eIF3f, SARS ORF6, Dengue virus 1 core protein gene) were inserted into various positions of the IBV genome, and the effects on gene expression, virus recovery, and stability in cell culture were studied. Selected viruses were also inoculated into chicken embryos for studies of foreign gene expression at different tissue level. The results demonstrated the stability of recombinant viruses depends on the intrinsic properties of the foreign gene itself as well as the position at which the foreign genes were inserted. For unstable viruses, the loss of expression of the inserted genes was found to result from a large deletion of the inserted gene and even IBV backbone sequences. This represents a promising system for development of coronavirus-based gene delivery vectors and vaccines against coronavirus and other viral infections in chicken.
