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
The full-length cDNA sequence of a trehalose-6-phosphate synthase gene from Saccharina japonica (designated as SjaTPS) (Accession: KC578568) was isolated based on homologous cloning and RACE-PCR. It was 4,127 bp, with 320 bp 5'-UTR, 21 bp 3'-UTR, and open reading frame (ORF) of 3,786 bp. The deduced 1,261 amino acids characterized with predicted molecular weight of 137.84 kDa and theoretical isoelectric point of 7.12. The SjaTPS had one N-terminal CBM20 (family 20 carbohydrate-binding module) domain, one TPS domain (trehalose-6-phosphate synthase) in the middle region and a single TPP (trehalose-6-phosphate phosphatase) domain near the C-terminus. Structural analysis suggested that the SjaTPS putatively functioned as trehalose-6-phosphate synthase, and might be related to laminaran metabolism in S. japonica. Homology analysis indicated that the SjaTPS shared 49-70 % similarities with the 13 known TPS sequences of other algae; only 55 % amino acid similarities were detected between SjaTPS and the previously reported TPS sequence of S. japonica (Accession: DQ666325). Phylogenetic analysis revealed close affinity between SjaTPS and TPS of brown alga Ectocarpus siliculosus (Accession: CBJ29609). Transcriptional analysis showed that desiccation greatly enhanced SjaTPS expression and the maximum appeared at 3 h, which was about 300-fold compared to that of the start, implied that SjaTPS was involved with drought adaption in kelp. In vitro expression of SjaTPS showed that one distinct band existed at ~115 kDa, and western blot detection proved that it was positive to the anti-His antibody with high specificity. Our results increased the knowledge of trehalose-6-phosphate synthase properties in S. japonica and also important for better understanding the role trehalose plays in kelp abiotic tolerance for adaption to the sublittoral habitats.
