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 previously identified a chloroplast-derived (ct-derived) sequence of 32 base pairs (bp) in rice mitochondrial DNA that includes a part (30 bp; psitrnI) of a gene for isoleucine tRNA (CAU) of the chloroplast. Analyzing the ct-derived psitrnI, we found that an open reading frame (orf240), which was homologous to the gene for a subunit of an ATP-binding cassette-type (ABC-type) heme transporter, namely helC, of Rhodobacter capsulatus, and a gene for subunit 6 of NADH dehydrogenase (nad6) were located upstream of and downstream from the ct-derived psitrnI, respectively. Northern-blot hybridization and analysis by reverse transcription-polymerase chain reaction (RT-PCR) revealed that both orf240 and nad6 were co-transcribed in rice mitochondria. An analysis of PCR-amplified fragments of the region of orf240/nad6 from the DNA of some Gramineae suggests that the arrangement of orf240/nad6 was generated in the mitochondrial genome of the genus Oryza during evolution after its divergence from the other Gramineae. Most of the transcripts of orf240 are edited, with a change from cytidine to uridine, at 35 positions. Editing of the RNA changes 33 amino-acid residues among the 240 encoded amino-acid residues, suggesting that the orf240 gene is functional in rice mitochondria.
