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 messageJasmonate-induced accumulation of anti-herbivore compounds mediates rice resistance to the leaf folder Cnaphalocrocis medinalis. The rice leaf folder (LF), Cnaphalocrocis medinalis, is one of the most destructive insect pests in the paddy field. LF larvae induces leaf folding and scrapes the upper epidermis and mesophyll tissues reducing photosynthesis and yield in rice. Identifying plant defense pathways and genes involved in LF resistance is essential to understand better this plant-insect interaction and develop new control strategies for this pest. Jasmonate (JA) signaling controls a plethora of plant defenses against herbivores. Using RNA-seq time series analysis, we characterized changes in the transcriptome of wild-type (WT) leaves in response to LF damage and measured the dynamics of accumulation of JA phytohormone pools in time-course experiments. Genes related to JA signaling and responses, known to mediate resistance responses to herbivores, were induced by LF and were accompanied by an increment in the levels of JA pools in damaged leaves. The accumulation of defense compounds such as phenolamides and trypsin proteinase inhibitor (TPI) also increased after LF infestation in WT but not in JA mutant plants impaired in JA biosynthesis (aoc-2) and signaling (myc2-5). Consistent with all these responses, we found that LF larvae performed better in the JA mutant backgrounds than in the WT plants. Our results show that JA signaling regulates LF-induced accumulation of TPI and phenolamides and that these compounds are likely an essential part of the defense arsenal of rice plants against this insect pest.
