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 putative Type II restriction-modification system of Thermotoga neapolitana, TneDI, was cloned into Escherichia coli XL1-Blue MRF' and characterized. Gene CTN_0339 specifies the endonuclease R.TneDI, while CTN_0340 encodes the cognate DNA methyltransferase M.TneDI. Both enzymes were purified simply by heating the cell lysates of E. coli followed by centrifugation. The enzymes were active over a broad range of temperatures, from 42°C to at least 77°C, with the highest activities observed at 77°C. R.TneDI cleaved at the center of the recognition sequence (CG↓CG) and generated blunt-end cuts. Overexpression of R.TneDI in BL21(DE3) was confirmed by both SDS-PAGE and Western blotting.
