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
Lectins selectively recognize sugars or glycans for defense in living cells, but less is known about their roles in the development process and the functional network with other factors. Here, we show that Arabidopsis (Arabidopsis thaliana) JACALIN-LECTIN LIKE1 (AtJAC1) functions in flowering time control. Loss of function of AtJAC1 leads to precocious flowering, whereas overexpression of AtJAC1 causes delayed flowering. AtJAC1 influences flowering through regulation of the key flowering repressor gene FLOWERING LOCUS C (FLC). Genetic analysis revealed that AtJAC1's function is mostly dependent on GLYCINE-RICH RNA-BINDING PROTEIN7 (GRP7), an upstream regulator of FLC. Biochemical and cell biological data indicated that AtJAC1 interacted physically with GRP7 specifically in the cytoplasm. AtJAC1 influences the nucleocytoplasmic distribution of GRP7, with predominant nuclear localization of GRP7 when AtJAC1 function is lost but retention of GRP7 in the cytoplasm when AtJAC1 is overexpressed. A temporal inducible assay suggested that AtJAC1's regulation of flowering could be compromised by the nuclear accumulation of GRP7. In addition, GRP7 binds to the antisense precursor messenger RNA of FLC through a conserved RNA motif. Loss of GRP7 function leads to the elevation of total FLC antisense transcripts and reduced proximal-distal polyadenylation ratio, as well as histone methylation changes in the FLC gene body region and increased total functional sense FLC transcript. Attenuating the direct binding of GRP7 with competing artificial RNAs leads to changes of FLC antisense precursor messenger RNA processing and flowering transition. Taken together, our study indicates that AtJAC1 coordinates with GRP7 in shaping plant development through the regulation of RNA processing in Arabidopsis.
