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
key messageSlPRE2 is gibberellin inducible and mediates plant response to gibberellin. Silencing of SlPRE2 decreases tomato fruit size, pericarp thickness, placenta size and seed size by regulating cell expansion. Gibberellin is one of the crucial hormones essential for plant growth and developmental processes, including seed germination, stem elongation, and sex expression. Previous studies indicated gibberellin could control fruit development by regulation of genes downstream gibberellin pathway. In the present study, we found that the SlPRE2, a bHLH family transcription factor gene, is highly expressed in immature green fruit. Silencing of SlPRE2 caused reduction of fruits size, pericarp thickness, and placenta size. Meanwhile, smaller seeds were observed in SlPRE2 silenced lines. In addition, the SlPRE2-silenced fruit mesocarp had reduced cell size and expression of SlXTH2 and SlXTH5 which are involved in cell enlargement. Further research showed that SlPRE2 is gibberellic acid-inducible and the expression of gibberellin metabolism-related genes in immature green fruit was affected by the downregulation of SlPRE2. Moreover, the SlPRE2-silenced plants had changed responses to application of exogenous gibberellic acid and paclobutrazol, an inhibitor of gibberellin biosynthesis. These findings indicated that SlPRE2 is a regulator of fruit development and affects plant response to gibberellic acid via the gibberellin pathway.
