P2 of Rice grassy stunt virus (RGSV) and p6 and p9 of Rice ragged stunt virus (RRSV) isolates from Vietnam exert suppressor activity on the RNA silencing pathway.
Article in Virus genes, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
In Vietnam, the two main viruses that cause disease in rice are the Rice grassy stunt virus (RGSV) and the Rice ragged stunt virus (RRSV). Outbreaks of these two viruses have dramatically decreased rice production in Vietnam. Because natural resistance genes are unknown, an RNAi strategy may be an alternative method to develop resistance to RGSV and RRSV. However, this strategy will be efficient only if putative silencing suppressors encoded by the two viruses are neutralized. To identify these suppressors, we used the classical green fluorescent protein (GFP) agroinfiltration method in Nicotiana benthamiana. Then, we investigated the effects of viral candidate proteins on GFP expression and GFP siRNA accumulation and their interference with the short- or long-range signal of silencing. RGSV genes s2gp1, s5gp2, and s6gp1 and RRSV genes s5gp1, s6gp1, s9gp1, and s10gp1 were selected for viral silencing suppressor investigation according to their small molecular weight, the presence of cysteines, or the presence of a GW motif in related protein products. We confirmed that protein p6 of RRSV displays mild silencing suppressor activity and affects long-range silencing by delaying the systemic silencing signal. In addition, we identified two new silencing suppressors that displayed mild activity: p2 of RGSV and p9 of RRSV.
