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
MicroRNA164 (miR164) plays a key role in leaf and flower development, lateral root initiation, and stress responses. However, little is known about the regulatory roles of miR164 during seed development, particularly in maize. The aim of this study was to discover the developmental function of miR164 in maize seed. Small RNA sequencing (sRNA-seq) was performed at two key stages. The results indicated that miR164 was down-regulated during maize seed development. In addition, degradome library sequencing and transient expression assays identified the target genes for miR164. Two microRNA (miRNA) pairs, miR164-NAM, ATAF, and CUC32 (NAC32) and miR164-NAC40, were isolated. The developmental function of miR164 was determined by analyzing the differentially expressed genes (DEGs) between the wild-type and miR164 transgenic lines using RNA sequencing (RNA-seq) and by screening the DEGs related to NAC32 and NAC40 via co-expression and transient expression analysis. These results identified two beta-expansin genes, EXPB14 and EXPB15, which were located downstream of the NAC32 and NAC40 genes. This study revealed, for the first time, a miR164-dependent regulatory pathway, miR164-NAC32/NAC40-EXPB14/EXPB15, which participates in maize seed expansion. These findings highlight the significance of miR164 in maize seed development, and can be used to explore the role of miRNA in seed development.
