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
During rice seed development, prolamine RNAs are localized to the surface of the prolamine storage protein bodies (PBs), organelles bounded by the endoplasmic reticulum (ER). The exact mechanism by which prolamine RNAs are enriched on this ER subdomain is not known but recent evidence indicates the directed transport and targeting of prolamine RNAs to the prolamine PBs. As such a process involves RNA signal determinants and cytoskeleton-interacting proteins that recognize these signals, we obtained an enriched cytoskeleton-PB fraction and identified a prominent RNA-binding activity, Rp120, by RNA-binding UV-cross-linking assay. Recombinant cDNA clones of Rp120 revealed that the primary sequence shared considerable structural homology to the human transcriptional coactivator p100 and possessed a modular organization, four nucleic acid-binding SN domains, a tudor domain and a coil-coil domain. Consistent with the presence of SN domains, Rp120 binds a variety of RNAs including prolamine RNA. Interaction with the latter RNA, however, was specific as binding activity was evident only to the prolamine 3' UTR and not to the 5' UTR or coding sequences. Rp120 is also able to interact with other proteins as its sedimentation behavior in sucrose density gradient suggests an association with the cytoskeleton. The presence of a tudor domain, suggested to have a role in RNA processing or transport, together with the SN and coiled-coil domains are consistent with the view that Rp120 may be involved in RNA sorting in rice endosperm.
