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
WRKY proteins are a large super family of transcriptional regulators primarily involved in various plant physiological programs. In present study, the expression profile and putative function of the WRKY transcriptional factor, WRKY78, in rice were identified. Real-time RT-PCR analysis showed that OsWRKY78 transcript was most abundant in elongating stems though its expression was detected in all the tested organs. The expression profiles were further confirmed by using promoter-GUS analysis in transgenic rice. OsWRKY78::GFP fusion gene transient expression analysis demonstrated that OsWRKY78 targeted to the nuclei of onion epidermal cell. Furthermore, OsWRKY78 RNAi and overexpression transgenic rice lines were generated. Transgenic plants with OsWRKY78 overexpression exhibited a phenotype identical to the wild type, whereas inhibition of OsWRKY78 expression resulted in a semi-dwarf and small kernel phenotype due to reduced cell length in transgenic plants. In addition, a T-DNA insertion mutant line oswrky78 was identified and a phenotype similar to that of RNAi plants was also observed. Grain quality analysis data showed no significant differences, with the exception of minor changes in endosperm starch crystal structure in RNAi plants. Taken together, these results suggest that OsWRKY78 may acts as a stem elongation and seed development regulator in rice.
