1 · What the graph read from it

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.

2 · The registry

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

A group I intron interrupts the tRNA(Arg)CCU gene of the alpha-purple bacterium Agrobacterium tumefaciens (B. Reinhold-Hurek and D. A. Shub, Nature [London] 357:173-176, 1992). In this study, we assess the distribution of the corresponding intron among 12 additional species of alpha-purple bacteria. Of 10 newly identified tRNA(Arg)CCU genes, we found only two that contained an intron homologous to that of the Agrobacterium intron. This restricted and scattered distribution of the tRNA(Arg)CCUg intron among alpha-purple bacteria is consistent with a recent origin and horizontal transmission. Primary and secondary structural similarities between tRNA(Leu)UAA introns found in strains of the cyanobacterium Microcystis aeruginosa (K. Rudi and K. S. Jacobsen, FEMS Microbiol. Lett. 156:293-298, 1997) and alpha-purple tRNA(Arg)CCU introns suggest that these introns share a more recent common ancestor than either does with other known cyanobacterial tRNA(Leu)UAA introns.
