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
The leucine-rich repeat class of receptor-like kinase (LRR-RLKs) encoding genes represents the largest family of putative receptor genes in the Arabidopsis thaliana genome. However, very little is known about the range of biological process that they control. We present in this paper the functional characterization of RLK7 that has all the structural features of a receptor-like kinase of the plant-specific LRR type. To this end, we identified and characterized three independent T-DNA insertion mutants, constructed lines carrying truncated versions of this putative receptor, one lacking the cytoplasmic kinase domain (RLK7Δkin) and the other one lacking 14 LRR repeats (RLK7ΔLRR) and generated RLK7 overexpressing lines. We thus provide evidences that RLK7 is involved in the control of germination speed and the tolerance to oxidant stress. First, consistent with the expression kinetics of the RLK7 gene in the seeds, we found that all three mutants showed a delay in germination, whereas the overexpressors, RLK7Δkin and RLK7ΔLRR lines displayed a phenotype of more precocious germination. Second, a non-hypothesis driven proteomic approach revealed that in the seedlings of the three T-DNA insertion lines, four enzymes directly or indirectly involved in reactive oxygen species detoxification, were significantly less abundant. Consistent with this finding, the three mutants were less tolerant than the wild type to a hydrogen peroxide treatment, whereas the overexpressors, RLK7Δkin and RLK7ΔLRR lines presented the opposite phenotype.
