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
Sugar transport plays a pivotal role in determining the productivity of plants and their capacity to act as carbon sinks. In the major fruit crop grapevine (Vitis vinifera L.), the transporter gene V. vinifera Sugars Will Eventually be Exported Transporter 15 (VvSWEET15) is strongly expressed during berry ripening. However, the specific functions of VvSWEET15 and the mechanisms governing its transcriptional regulation remain largely unresolved. Here, we demonstrate that VvSWEET15 functions as a hexose transporter whose expression is associated with the strong sugar accumulation that starts at the véraison stage. We also characterize VvERF105 as a repressor that binds to the LTR-binding element in the VvSWEET15 promoter, thereby downregulating its expression and inhibiting hexose accumulation at the prevéraison stage. In contrast, VvNAC72 is an activator that binds to the VvNAC72-binding domain (CACATG) and promotes VvSWEET15 expression and hexose accumulation at postvéraison stages. Both transcription factors and VvSWEET15 are preferentially expressed in phloem cells. These results demonstrate that the balance between transcriptional activators and repressors is critical in regulating VvSWEET15 expression in sink organs. Further understanding of these processes will help improve plant productivity and their potential to be used as carbon sinks.
