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
Introduction: Drought stress severely constrains grape growth and productivity, yet the molecular mechanisms underlying drought adaptation remain incompletely understood. This study aimed to identify key transcriptional regulators involved in grape drought responses and to evaluate their functional roles. Methods: To address this, callus tissues derived from Results: Transcriptome analysis identified 48 transcription factor families involved in drought response, among which the MYB family was the most abundant. Functional analyses showed that OE- Discussion: These results indicate that VvMYB1 functions as a positive regulator in grape drought response. This study provides new insights into the transcriptional regulation of drought tolerance in grape and identifies VvMYB1 as a promising candidate gene for improving stress resilience.
