RNA editing of mat-r transcripts in maize and soybean increases similarity of the encoded protein to fungal and bryophyte group II intron maturases: evidence that mat-r encodes a functional protein.
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 17 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
We present evidence that transcripts of the mat-r (maturase-related) genes of maize and soybean contain 15 and 14 uridines (U), respectively, at positions occupied by cytosines (C) in the mat-r gene sequences. Eleven and twelve of these C-->U edits result in an amino acid replacement. Ten C-->U edits are at corresponding nucleotides in the maize and soybean transcripts and, except for a single silent edit, the remainder are at positions in one species that are Us in the other species. This results in an increase in amino acid sequence similarity of the maize and soybean MAT-R proteins. Further, of those amino acids in maize and soybean MAT-R proteins specified by edited codons, ten are conserved in the reverse transcriptase-associated and RNA splicing-associated sequences of the cox1-I2 and/or the cox1-I1 maturases of the fungus Saccharomyces cerevisiae and the bryophyte, Marchantia polymorpha, respectively. The implied strong selection for amino acid sequence conservation indicates that the MAT-R protein is functional. The possibility is discussed that initiation of translation of the mat-r transcripts is at a four nucleotide codon, ATAA or ATGA.
