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
Thus far, no transcription factor IIIA (TFIIIA) from higher plants has been cloned and characterized. We have cloned and characterized TFIIIA and ribosomal protein L5 from Arabidopsis thaliana. Primary sequence comparison revealed a high divergence of AtTFIIIA and a relatively high conservation of AtL5 when compared with other organisms. The AtTFIIIA cDNA encodes a protein with nine Cys(2)-His(2)-type zinc fingers, a 23 amino acid spacer between fingers 1 and 2, a 66 amino acid spacer between fingers 4 and 5, and a 50 amino acid non-finger C-terminal tail. Aside from the amino acids required for proper zinc finger folding, AtTFIIIA is highly divergent from other known TFIIIAs. AtTFIIIA can bind 5S rDNA, as well as 5S rRNA, and efficiently stimulates the transcription of an Arabidopsis 5S rRNA gene in vitro. AtL5 identity was confirmed by demonstrating that this protein binds to 5S rRNA but not to 5S rDNA. Protoplast transient expression assays with green fluorescent protein fusion proteins revealed that AtTFIIIA is absent from the cytoplasm and concentrated at several nuclear foci including the nucleolus. AtL5 protein accumulates in the nucleus, especially in the nucleolus, and is also present in the cytoplasm.
