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 specific type II restriction endonuclease T.Smu451I has been purified to electrophoretic homogeneity from the frozen cells of soil bacterium Sphingobacterium multivorum 451 (formerly Flavobacterium multivorum 451), using ultrasonic grinding, nucleic acid removal by streptomycin sulfate, protein precipitation by ammonium sulfate and phosphocellulose P-11, DEAE-Cellulose DE-52, Hepharin-Sepharose CL-6B chromatography, and elucidated several characteristics of T.Smu451I. The molecular weight of the enzyme determined by gel filtration and SDS-polyacrylamide gel electrophoresis was calculated to be 45,000 ± 2000 D (dimer) and 23,000 ± 1000 D (monomer), respectively. The isoelectric point (pI) of T.Smu451I is 5.4. T.Smu451I recognizes pentanucleotide palindromic sequences 5'-GGNC↓C-3' and cleaves between C and C in position shown by arrow to produce 3'-cohesive terminus of trinucleotide. Therefore, T.Smu451I is a neoschizomer of T.AsuI.
