A common core structure for U3 small nucleolar RNAs.
Article in Nucleic acids research, 1994. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 22 papers.
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
U3 nucleolar small RNA (snRNA) is involved in early processing of the primary rRNA transcript. A secondary structure model for the unusually small Trypanosoma brucei U3 snRNA was deduced by chemical modification and enzymatic cleavage of U3 snRNA in deproteinized and ribonucleoprotein (RNP) forms. Comprehensive alignment of U3 snRNAs from vertebrate, plant, fungal and protozoan species clearly delineated conserved and divergent features. The 5' domain of the T. brucei U3 snRNA appears to form one small, flexible 5' stem loop structure followed by a long single-stranded region; this model is a variation on 5' domain structures proposed for other U3 snRNAs which do not conform to a single model. The 3' domain of T. brucei U3 snRNA contains four single-stranded sequences conserved between U3 snRNAs. Of these, structural probing determined that the configurations of GAU region and box B and C sequences are altered by protein interactions in U3 snRNP. Conspicuously, the 3' domains of trypanosomal U3 snRNAs lack stem loops II and III, indicating that these structures are not required for conserved U3 snRNA functions.
