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
TGA factors constitute a family of conserved plant bZ1P transcription factors that regulate transcription from as-1-like elements in response to plant signalling molecules salicylic acid (SA), methyl jasmonate (MJ) and auxin. Based on sequence similarities, two subclasses of TGA factors have been identified before in tobacco: class I factors (TGA1a and PG13) are preferentially expressed in root tip meristems, whereas class II factors (TGA2.1 and TGA2.2) are found in leaves and in roots. Here we describe a novel member of the tobacco TGA family (TGA10), which defines a distinct subclass of its own. TGA10 mRNA and TGA10 protein were found in roots but not in leaves of mature tobacco plants. TGA10 binds specifically to the as-1 element, interacts with TGA2.2, and activates transcription in yeast. When ectopically expressed in leaves, TGA10 enhanced SA-, auxin- and MJ-inducibility of target gene Nt103, which responds in the same manner to enhanced levels of TGA2.2. This indicates that TGA10, albeit normally not present in leaves, can interact with the leaf regulatory network controlling transcription from as-1-containing promoters. However, Nt103 expression was not affected in roots of TGA10-over-expressing plants, implying the existence of root-specific mechanisms which do not allow a positive effect of increased TGA10 levels on target gene expression.
