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
MAIN
conclusionA rice MYB transcription factor, OsMYB58/63, was found to directly upregulate the expression of a rice secondary wall-specific cellulose synthase gene, cellulose synthase A7 ( OsCesA7 ); in contrast, the Arabidopsis putative orthologs AtMYB58 and AtMYB63 have been shown to specifically activate lignin biosynthesis. Although indirect evidence has shown that grass plants are similar to but partially different from dicotyledonous ones in transcriptional regulation of lignocellulose biosynthesis, little is known about the differences. This study showed that a rice MYB transcription factor, OsMYB58/63, directly upregulated the expression of a rice secondary wall-specific cellulose synthase gene, cellulose synthase A7 (OsCesA7). Gene co-expression analysis showed that, in rice, OsMYB58/63 and several rice MYB genes were co-expressed with genes encoding lignocellulose biosynthetic enzymes. The expression levels of OsMYB55/61, OsMYB55/61-L, OsMYB58/63, and OsMYB42/85 were commonly found to be high in culm internodes and nodes. All four MYB transcription factors functioned as transcriptional activators in yeast cells. OsMYB58/63 most strongly transactivated the expression of OsCesA7 in rice protoplasts. Moreover, recombinant OsMYB58/63 protein was bound to two distinct cis-regulatory elements, AC-II and SMRE3, in the OsCesA7 promoter. This is in sharp contrast to the role of Arabidopsis orthologs, AtMYB58 and AtMYB63, which had been reported to specifically activate lignin biosynthesis. The promoter analysis revealed that AC elements, which are the binding sites for MYB58 and MYB63, were lacking in cellulose and xylan biosynthetic genes in Arabidopsis, but present in cellulose, xylan, and lignin biosynthetic genes in rice, implying that the difference of transcriptional regulation between rice and Arabidopsis is due to the distinct composition of promoters. Our results provide a new insight into transcriptional regulation in grass lignocellulose biosynthesis.
