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
How or whether organisms can inherit parental adaptations to the prevailing environment is a major topic in biology. In plants, seed traits such as size, yield, and dormancy are all affected by the environment during reproduction, but whether developing progeny sense temperature within the fruit or whether seasonal climate information is inherited intergenerationally from the parents remains unclear. In this study, we use intergenerational single-nucleus omics to understand the mechanisms underlying the effects of seasonal temperature changes in fruits containing developing seeds of the next generation. We show that the sensing of temperature takes place specifically in maternal fruit tissues and that mothers preadapt their progeny to maternal temperature through the intergenerational flux of the hormone ABA to the zygote itself where it is sensed to affect dormancy. We conclude that mothers can control filial traits via direct transfer of hormones to progeny and propose that this is an important mechanism by which populations can rapidly adapt to environmental change.
