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
Retinoid-X-receptor (RXR) plays an essential role in the molting process of decapod crustaceans, by forming a heterodimeric complex with the ecdysteroid receptor. However, its role during female reproduction, especially in the process of ovarian maturation, has not been characterized. To get an insight into the molecular events governing the process of ovarian maturation in shrimps, the full-length cDNA of RXR from Metapenaeus ensis was cloned by extension of truncated cDNA by using the RACE technique. The open reading frame of MeRXR encodes a 410 amino acid protein with a deduced molecular weight of 44.8 kDa, and putative pI of 6.64, which roughly matched our observation from 2DE gel. Phylogenetic analysis showed that MeRXR has high similarity to RXR of Penaeus chinensis and P. japonicus. RT-PCR revealed that MeRXR was universally expressed in all tissues investigated. The variation in MeRXR mRNA expression pattern during ovarian maturation was further analyzed by real-time PCR. In contrast to the decrease in MeRXR at protein level with ovarian maturation, MeRXR mRNA level was low in pre-vitellogenic and mid-vitellogenic ovaries, and increased significantly from mid-vitellogenic to late-vitellogenic stages. This result suggests that MeRXR transcripts in the mature ovary probably act as maternal messages for regulating early molting events during embryonic development.
