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
Calcium/calmodulin (Ca(2+)/CaM) has long been considered a crucial component in wound signaling pathway. However, very few Ca(2+)/CaM-binding proteins have been identified which regulate plant responses to herbivore attack/wounding stress. We have reported earlier that a family of Ca(2+)/CaM-binding transcription factors designated as AtSRs (also known as AtCAMTAs) can respond differentially to wounding stress. Further studies revealed that AtSR1/CAMTA3 is a negative regulator of plant defense, and Ca(2+)/CaM-binding to AtSR1 is indispensable for the suppression of salicylic acid (SA) accumulation and disease resistance. Here we report that Ca(2+)/CaM-binding is also critical for AtSR1-mediated herbivore-induced wound response. Interestingly, atsr1 mutant plants are more susceptible to herbivore attack than wild-type plants. Complementation of atsr1 mutant plants by overexpressing wild-type AtSR1 protein can effectively restore plant resistance to herbivore attack. However, when mutants of AtSR1 with impaired CaM-binding ability were overexpressed in atsr1 mutant plants, plant resistance to herbivore attack was not restored, suggesting a key role for Ca(2+)/CaM-binding in wound signaling. Furthermore, it was observed that elevated SA levels in atsr1 mutant plants have a negative impact on both basal and induced biosynthesis of jasmonates (JA). These results revealed that Ca(2+)/CaM-mediated signaling regulates plant response to herbivore attack/wounding by modulating the SA-JA crosstalk through AtSR1.
