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
Previous work has shown that transgenic tobacco plants constitutively over-expressing the Vitis vinifera L. transcription factor VvWRKY2 exhibit reduced susceptibility to necrotrophic fungal pathogens, suggesting that this transcription factor plays a role in grapevine response to phytopathogens. The work presented here characterizes the modifications in cell wall structure observed in the stems and petioles of these transgenic plants. Histochemical stainings of stem and petiole cross-sections using phloroglucinol or Maüle reagents revealed a delay in xylem formation, particularly in the petioles, and differences in lignin composition. Evaluation of lignin quantity and quality showed a decrease in the syringyl/guaiacyl ratio in both stem and petioles. Expression analysis using RT-PCR and potato microarrays showed that tobacco plants over-expressing VvWRKY2 exhibited altered expression of genes involved in lignin biosynthesis pathway and cell wall formation. The ability of VvWRKY2 to activate the promoter of the VvC4H gene, which is involved in the lignin biosynthetic pathway, was confirmed by transient transcriptional activation assays in tobacco protoplasts. Moreover, in situ hybridization revealed that VvWRKY2 is specifically expressed in cells undergoing lignification in young grapevine stems. Together, these results confirm that VvWRKY2 plays a role in regulating lignification in grapevine, possibly in response to biotic or abiotic stresses.
