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
We report here the cloning and characterization of a soybean receptor-like kinase (RLK) gene, designated GmSARK (Glycine max senescence-associated receptor-like kinase), which is involved in regulating leaf senescence. The conceptual protein product of GmSARK contains typical domains of LRR receptor-like kinases: a cytoplasmic domain with all the 11 kinase subdomains, a transmembrane domain and an extracelullar domain containing 9 Leucine-Rich Repeat (LRR) units that may act as a receptor. The expression of GmSARK in soybean leaves was up-regulated in all the three tested senescence systems: senescing cotyledons, dark-induced primary leaf senescence and the natural leaf senescence process after florescence. Furthermore, the RNA interference (RNAi)-mediated knocking-down of GmSARK dramatically retarded soybean leaf senescence. A more complex thylakoid membrane system, higher foliar level of chlorophyll content and a very remarkable delay of senescence-induced disintegration of chloroplast structure were observed in GmSARK-RNAi transgenic leaves. A homolog of maize lethal leaf-spot 1 gene, which has been suggested to encode a key enzyme catalyzing chlorophyll breakdown, was isolated and nominated Gmlls1. The expression level of Gmgtr1 gene, which encodes a key enzyme of chlorophyll synthesis, was also analyzed. It was found that Gmlls1 was up-regulated and Gmgtr1 was down-regulated during senescence in wild-type soybean leaves. However, both of the up-regulation of Gmlls1 and down-regulation of Gmgtr1 were retarded during senescence of GmSARK-RNAi transgenic leaves. In addition, over-expression of the GmSARK gene greatly accelerated the senescence progression of CaMV 35S:GmSARK transgenic plants. Taken together, these results strongly suggested the involvement of this LRR-RLK in regulation of soybean leaf senescence, maybe via regulating chloroplast development and chlorophyll accumulation. Multiple functions of GmSARK besides its regulation of leaf senescence were also discussed.
