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
MAIN
conclusionSugar transport, including the symplasmic pathway in plasmodesmata and apoplasmic pathway mediated by sugar transporters, accelerated sugar accumulation in cultivated jujube, while sugar metabolism-related genes played weak roles in jujube domestication. The fruit of Chinese jujube (Ziziphus jujuba Mill.) is high in sugar concentration. By contrast, wild type-sour jujube (Z. jujuba Mill. var. spinosa Hu) contains markedly less sugar. It is unknown whether sugar transport or sugar metabolism drove sugar accumulation during jujube domestication. Using a combination of ultrastructural observations, phylogenetic analysis, testing for soluble sugars, and transcriptional analysis, the sugar accumulation mechanism was studied in the developmental stages of cultivated jujube and sour jujube. Our results indicate that the symplasmic transport pathway in plasmodesmata is present in cultivated jujube, but not in sour jujube. Sugar transporter genes have higher frequencies of duplication than sugar metabolism-related genes. Gene expression patterns indicate that sugar transporter genes, especially ZjSUT2, ZjSWEET1, ZjSWEET7, ZjSWEET11, ZjSTP3, and ZjSTP13a, rather than sugar metabolism-related genes showed higher expression levels in cultivated jujube versus sour jujube during fruit sugar accumulation. These findings suggest that sugar transport, including apoplasmic and symplasmic transport, rather than sugar biosynthesis, is associated with the difference in sugar accumulation between jujube and sour jujube, and that it may drive jujube domestication. This study provides valuable genetic information for jujube improvement, and offers new insights into fruit tree domestication related to sugar accumulation.
