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
Rice (Oryza sativa L.) microRNA156/529-SQUAMOSA PROMOTER BINDING PROTEIN-LIKE7/14/17 (miR156/529-SPL7/14/17) modules have pleiotropic effects on many biological pathways. OsSPL7/14 can interact with DELLA protein SLENDER RICE1 (SLR1) to modulate gibberellin acid (GA) signal transduction against the bacterial pathogen Xanthomonas oryzae pv. oryzae. However, whether the miR156/529-OsSPL7/14/17 modules also regulate resistance against other pathogens is unclear. Notably, OsSPL7/14/17 functioning as transcriptional activators, their target genes, and the corresponding downstream signaling pathways remain largely unexplored. Here, we demonstrate that miR156/529 play negative roles in plant immunity and that miR156/529-regulated OsSPL7/14/17 confer broad-spectrum resistance against 2 devastating bacterial pathogens. Three OsSPL7/14/17 proteins directly bind to the promoters of rice Allene Oxide Synthase 2 (OsAOS2) and NONEXPRESSOR OF PATHOGENESIS-RELATED GENES1 (OsNPR1) and activate their transcription, regulating jasmonic acid (JA) accumulation and the salicylic acid (SA) signaling pathway, respectively. Overexpression of OsAOS2 or OsNPR1 impairs the susceptibility of the osspl7/14/17 triple mutant. Exogenous application of JA enhances resistance of the osspl7/14/17 triple mutant and the miR156 overexpressing plants. In addition, genetic evidence confirms that bacterial pathogen-activated miR156/529 negatively regulate pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI) responses, such as pattern recognition receptor Xa3/Xa26-initiated PTI. Our findings demonstrate that bacterial pathogens modulate miR156/529-OsSPL7/14/17 modules to suppress OsAOS2-catalyzed JA accumulation and the OsNPR1-promoted SA signaling pathway, facilitating pathogen infection. The uncovered miR156/529-OsSPL7/14/17-OsAOS2/OsNPR1 regulatory network provides a potential strategy to genetically improve rice disease resistance.
