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
The nucleotide sequences of the tRNASer (trnS), pseudo-tRNA, NADH dehydrogenase subunit 3 (nad3), and ribosomal protein S12 (rps12) genes from rice mitochondrial DNA (mtDNA) were determined. Both trnS and nad3 were confirmed to be single copy genes by Southern blot analysis. The nad3 and rps12 genes were arranged in tandem, and the two were co-transcribed. The order of the above four genes in rice mtDNA differed from the linear order observed for the wheat and maize genes. In rice mitochondria, the trnS and pseudo-tRNA genes were found upstream of the cytochrome c oxidase subunit I gene, instead of the nad3 and rps12 genes as observed in maize and wheat. Additionally, while the rice nad3 and rps12 genes remain paired, they too are in a different sequence environment from the wheat and maize genes. The apparent split of the two pairs of genes indicates the occurrence of a mitochondrial intramolecular recombinational event. Another peculiarity is that the sequence upstream of the translational initiation codon of the rice nad3 gene is different from that of the wheat and maize versions. The ATG initiation codon of wheat and maize nad3 is replaced by TTG in the rice nad3. A subsequent deduction of the amino acid sequence, accompanied by a primer extension analysis, indicates that the predicted rice NAD3 protein has an additional 37 amino acid residues at its N-terminus compared to the wheat and maize NAD3 proteins. cDNA sequence analysis showed no introns or the occurrence of RNA editing at the newly replaced TTG codon.
