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
Ethylene-responsive transcription factors (ERFs) bind specifically to cis-acting DNA regulatory elements such as GCC boxes and play an important role in the regulation of defense- and stress-related genes in plants. In contrast to other ERFs, class II ERFs contain an ERF-associated amphiphilic repression (EAR) domain and act as GCC-mediated transcriptional repressors. In this study, SlERF3, a class II ERF was isolated from tomato and characterized. To examine whether the EAR motif of class II ERF proteins participates in ERF-mediated functions in plants, the EAR domain was deleted to generate SlERF3ΔRD. We show that SlERF3ΔRD protein retains the character of a transcription factor and becomes a GCC-mediated transcriptional activator. Constitutive expression of full-length SlERF3 in tomato severely suppressed growth and, as a result, no transgenic plants were obtained. However, no apparent effects on growth and development of SlERF3ΔRD transgenic plants were observed. Overexpression of SlERF3ΔRD in transgenic tomato induced expression of pathogenesis-related protein genes such as PR1, PR2 and PR5, and enhanced tolerance to Ralstonia solanacearum. Furthermore, transgenic Arabidopsis and tomatoes constitutively expressing SlERF3ΔRD exhibited reduced levels of membrane lipid peroxidation and enhanced tolerance to salt stress. In comparison with wild-type plants grown under stress conditions, transgenic SlERF3ΔRD tomatoes produced more flowers, fruits, and seeds. This study illustrates a gene-enhancing tolerance to both biotic and abiotic stresses in transgenic plants with the deletion of a repressor domain. Our findings suggest that class II ERF proteins may find important use in crop improvement or genetic engineering to increase stress tolerance in plants.
