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
backgroundTrehalose 6-phosphate (Tre6P) synthase (TPS) and Tre6P phosphatase (TPP) are two key enzymes involved in the trehalose synthesis pathway in plants. However, the identification and research of TPS and TPP gene families in rye are still limited.
resultsIn this study, a total of 10 TPS genes and 9 TPP genes were identified based on the Lo7 genome database. According to phylogenetic analysis, ScTPS and ScTPP proteins from rye were more closely related to wheat, barley and other Triticeae species, and the fragment replication events might be the main driver of gene family expansion and new function generation during ScTPS and ScTPP genes evolution. Cis-element analysis revealed that ScTPS and ScTPP genes showed more stress-related cis-element distribution in rye, and some members of the ERF, MYB, bZIP, and C2H2 transcription factor families may play potential regulatory roles. Protein-protein interaction network analysis revealed that ScTPS07, ScTPS08, ScTPS09 and ScTPS10 might be hub genes in the rye trehalose synthesis pathway. RNA-seq and qRT-PCR analyses show that low temperature induces ScTPS and ScTPP expression; most genes reach maximal expression at 12-24 h; expression differs between roots and leaves of rye seedlings.
conclusionsThis study provided a molecular basis for trehalose synthesis in rye by identifying members of the ScTPS and ScTPP gene families, provided insights into the mechanism of cold stress tolerance of this substance in rye by preliminary analysis of the expression patterns of these genes under low temperature stress.
