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

Kiwifruit (Actinidia spp.) has long been appreciated for its desirable flavor and high nutritional value. In this study, leaf samples with chlorotic mottling symptoms were collected from kiwifruit plants in Hanzhong, Shaanxi Province of China. Using high-throughput sequencing, a novel totivirus tentatively designated Actinidia totivirus 1 (AcToV1) was identified. Its complete genome sequence was determined using RT-PCR and RACE techniques. The genome of AcToV1 is 5,060 nucleotides in length and contains two open reading frames (ORFs), encoding a coat protein (CP) of 793 amino acids and an RNA-dependent RNA polymerase (RdRp) of 841 amino acids. It also features a typical slippery heptanucleotide motif, a conserved element characteristic of the genus Totivirus. AcToV1 shares the highest genome-wide nucleotide sequence identity of 57.6% with Panax notoginseng virus A (PnVA; GenBank accession NO. KT388111). Its CP and RdRp also exhibit the highest amino acid sequence identities to PnVA, at 44.0% and 56.7%, respectively. Phylogenetic analysis further supported that AcToV1 clusters closely with PnVA and Hubei toti-like virus 2 (HTLV2). Therefore, AcToV1 be considered a new species of the genus Totivirus.
