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

purposeNewcastle disease (ND) represents a major viral disease across the world which imposes high costs to poultry producers for vaccination. Hemagglutinin-neuraminidase (HN) and fusion (F) proteins are the major immunogenic epitopes of Newcastle disease virus and hence, have been the main targets for development of anti-ND vaccines. This paper reports transient expression of a synthetic gene composing of four tandem repeats of HN and three tandem repeats of F epitopes in maize leaves as initial step toward production of recombinant vaccine against ND. MATERIALS AND

methodsThe synthetic gene was cloned in pBI121 plasmid to yield an expression vector. The vector was sophisticated by the addition of AUG codon, polyhistidine-tag, tobacco mosaic virus omega sequence, stop codon, and restriction sites. Leaf transformation was conducted by the agroinfiltration method. Molecular detection assays including polymerase chain reaction, reverse transcription-polymerase chain reaction and enzyme-linked immunosorbent assay (ELISA) were carried out to evaluate transgene expression in infiltrated leaves of the corn plant.

resultsThe result obtained in this research revealed that the transgene was transcribed and translated in maize leaves only 48 hours after infiltration. In the second phase of the experiment, the expressed protein was injected into rabbits. The result of the ELISA assay indicated induction of immune response in the rabbits after injection with the heterologous protein.

conclusionThese results confirm the feasibility of agroinfiltration for transient gene expression of viral epitopes in monocot plants which naturally resist stable transformation by
