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

Infectious cDNA clones are an important tool to study the molecular and cellular process of RNA virus infection. In vitro and in vivo transcription systems are the two main strategies used in the generation of infectious cDNA clones for RNA viruses. This study describes the first generation of a full-length infectious cDNA clone of Cowpea mild mottle virus (CPMMV), a Carlavirus. The full-length genome was synthesized by Overlap Extension PCR of two overlapping fragments and cloned in a pUC-based vector under control of the SP6 RNA polymerase promoter. After in vitro run-off transcription, the produced RNA was mechanically inoculated into soybean plants cv. CD206. The systemic infection was confirmed by RT-PCR and further sequencing of amplified cDNA fragments. To simplify the transfection process, the complete genome was subcloned into a binary vector under control of the 35S promoter of cauliflower mosaic virus by the Gibson Assembly protocol. The resulting clones were inoculated by particle bombardment onto soybean seedlings and the recovery of the virus was confirmed 2 weeks later by RT-PCR. Our results indicate the constructs of the full-length cDNA of CPMMV are fully infectious in both in vitro and in vivo transcription strategies.
