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
Chymotrypsin is one of the serine proteases families that have various biological functions. A chymotrypsin gene was isolated from hepatopancreas of the mud crab, Scylla paramamosain (designated SpCHY) in this study. The full-length cDNA of SpCHY contained 942 nucleotides with a polyadenylation sequence and encoded a peptide of 270 amino acids with a signal peptide of 17 amino acids. The SpCHY gene contains seven exons, six introns, a TATA box and several transcription factor binding sites that were found in 5'-promoter region which is 1221 bp in length. Real-time quantitative PCR analysis indicated that the expression level of SpCHY mRNA in hepatopancreas was significantly higher than that in other tissues. Immunocytochemistry and in situ hybridization exhibited the CHY-like reactivity presented in resorptive cells of the hepatopancreas. After bacterial challenge with Vibrio alginolyticus, the expression level of SpCHY mRNA was extremely up-regulated at 3 h in hepatopancreas. Our results suggest that SpCHY might play an important role in the mud crab's immune response.
