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 oriental river prawn Macrobrachium nipponense is an economically important aquacultural species. However, its aquaculture is negatively impacted by the rapid sexual maturation of female M. nipponense. The fast sexual maturation produces a large number of offspring which leads to a reduction in resilience, a low survival rate, and an increased risk of hypoxia, this in turn, seriously affects the economic benefits of prawn farming. Cathepsin D is a lysosomal protease involved in the ovarian maturation of M. nipponense. In the current study, the cDNA of the gene encoding cathepsin D (Mn-CTSD) was cloned from M. nipponense. The total length was 2391 bp and consisted of an open reading frame (ORF) of 1158 bp encoding 385 amino acids. Sequence analysis confirmed the presence of conserved N-glycosylation sites and characteristic sequences of nondigestive cathepsin D. The qPCR analysis indicated that Mn-CTSD was highly expressed in all tissues tested, most significantly in the ovaries, whereas in situ hybridization showed that expression occurred mainly in oocyte nuclei. Analysis of its expression during development showed that Mn-CTSD peaked during the O-IV stage of ovarian maturation. For the RNAi interference experiment, female M. nipponense specimens in the ovary stage I were selected. Injection of Mn-CTSD double-stranded (ds)RNA into female M. nipponense decreased the expression of Mn-CTSD in the ovaries, such that the Gonad Somatic Index (GSI) of the experimental group was significantly lower than that of the control group (1.79% versus 4.57%; p < 0.05). Ovary development reached the O-III stage in 80% of the control group, compared with 0% in the experimental group. These results suggest that Mn-CTSD dsRNA inhibits ovarian maturation in M. nipponense, highlighting its important role in ovarian maturation in this species and suggesting an approach to controlling ovarian maturation during M. nipponense aquaculture.
