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 gene that encodes the enzyme Pyrococcus furiosus cyclodextrin glucanotransferase (PFCGT) was cloned in Escherichia coli. PFCGT was highly expressed in recombinant E. coli after compensation for codon usage bias using the pRARE plasmid. Purified PFCGT was extremely thermostable with an optimal temperature and pH of 95 degrees C and 5.0, respectively, retaining 97% of its activity at 100 degrees C. Incubation at 60 degrees C for 20 min during the purification process led to a 1.5-fold increase in enzymatic activity. A time course assay of the PFCGT reaction with starch indicated that cyclic alpha-1,4-glucans with DPs greater than 20 were produced at the beginning of the incubation followed by an increase in beta-CD. The major final product of PFCGT cyclization was beta-CD, and thus the enzyme is a beta-CGTase.
