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
key messageOsNINJA1-interacting protein, OsSRO1a, acts as a mediator that suppresses OsMYC2 activity in response to JA. Jasmonic acid (JA) is an important plant hormone for the stable growth and development of higher plants. The rice gene NOVEL INTERACTOR OF JAZ1 (OsNINJA1) interacts with Jasmonate ZIM-domain (JAZ) proteins and is a repressor of JA signaling. In this study, we identified several OsNINJA1-interacting proteins in rice from a yeast two-hybrid screen. Among the newly identified genes, we focused on SIMILAR TO RCD ONE1a (OsSRO1a) and investigated its role in JA signaling. Full-length OsSRO1a interacted with OsNINJA1 in plant cells but not in yeast cells. OsSRO1a also interacted with OsMYC2, a positive transcription factor in JA signaling, in both plant and yeast cells. The expression of OsSRO1a was upregulated at a late phase after JA treatment. Transgenic rice plants overexpressing OsSRO1a exhibited JA-insensitive phenotypes. In wild-type plants, JA induces resistance against rice bacterial blight, but this phenotype was suppressed in the OsSRO1a-overexpressing plants. Furthermore, the degradation of chlorophyll under dark-induced senescence conditions and the JA-induced upregulation of OsMYC2-responsive genes were suppressed in the OsSRO1a-overexpressing plants. These results suggest that OsSRO1a is a negative regulator of the OsMYC2-mediated JA signaling pathway in rice.
