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
RNA-dependent RNA polymerases (RdRPs) in plants have been reported to be involved in post-transcriptional gene silencing (PTGS) and antiviral defense. In this report, an RdRP gene from maize (ZmRdRP1) was obtained by rapid amplification of cDNA ends (RACE) and RT-PCR. The mRNA of ZmRdRP1 was composed of 3785 nucleotides, including a 167 nt 5' untranslated region (UTR), a 291 nt 3'UTR and a 3327 nt open reading frame (ORF), which encodes a putative protein of 1108 amino acids with an estimated molecular mass of 126.9 kDa and a predicated isoelectric point (pI) of 8.37. Real-time quantitative RT-PCR analysis showed that ZmRdRP1 was elicited by salicylic acid (SA) treatment, methyl jasmonate (MeJA) treatment and sugarcane mosaic virus (SCMV) infection. We silenced ZmRdRP1 by constitutively expressing an inverted-repeat fragment of ZmRdRP1 (ir-RdRP1) in transgenic maize plants. Further studies revealed that the ir-RdRP1 transgenic plants were more susceptible to SCMV infection than wild type plants. Virus-infected transgenic maize plants developed more serious disease symptoms and accumulated more virus than wild type plants. These findings suggested that ZmRdRP1 was involved in antiviral defense in maize.
