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
Water limitation represents a major constraint in viticulture, affecting both physiological and molecular responses in grapevines. This study evaluated the physiological responses and scion transcriptomic profiles of two newly selected table grape genotypes, Genusia and Maula, grafted onto two contrasting rootstocks, 1103P (V. berlandieri × V. rupestris) and SO4 (V. berlandieri × V. riparia), under controlled water deficit conditions. Physiological measurements, including stomatal conductance and stem water potential, were integrated with RNA sequencing analyses to evaluate differential gene expression in actively growing shoots. Results revealed that rootstock identity significantly modulated scion responses to water limitation. SO4-grafted plants displayed a higher number of differentially expressed genes and a broader transcriptional reprogramming compared to 1103P, indicating a stronger molecular response to reduced water availability. Functional enrichment analyses indicated that SO4 combinations preferentially activated stress-related and defense-associated pathways, whereas 1103P combinations maintained a more stable expression of photosynthetic and primary metabolic processes. Overall, these findings highlight the central role of rootstock-scion interaction in shaping early physiological and transcriptional adjustments to water deficit and provide valuable insights for optimizing grafting combinations in table grape breeding programs to cope with water deficit.
