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
Seasonal temperature fluctuations serve as crucial environmental cues that regulate plant reproductive timing, yet the mechanisms underlying thermoresponsive flowering regulation in tomato remain poorly understood. The study uncovers a temperature-sensing mechanism in the tomato shoot apical meristem coordinated through antagonistic interactions between a florigen-like protein FLOWERING LOCUS T-Like 2 (FTL2) and florigen protein SINGLE-FLOWER TRUSS (SFT). Under short day conditions, FTL2 expression is specifically upregulated at the shoot apex by high temperature and functions as a flowering repressor. FTL2 physically interacts with the floral inducer SFT, directly suppressing its transcriptional activity to delay floral transition. This FTL2-SFT regulatory circuit enables tomato precise integration of photoperiodic and thermal signals at the shoot apex, providing a molecular framework for seasonal flowering adaptation. The findings elucidate a fundamental mechanism of temperature perception in tomato flowering control and provide broader insights into how florigen-based networks contribute to adaptive flowering control across plant species.
