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

We have cloned a pyr4 gene encoding orotidine-5'-monophosphate decarboxylase of the filamentous fungus Rhizopus niveus. The pyr4 gene of R. nivens has an open reading frame composed of 265 amino-acid residues and has two putative introns. We have also isolated a pyr4 mutant of Rhizopus delemar from 5-fluoroorotic acid-resistant mutants and transformed it with the pyr4 gene of R. niveus as a selectable marker. Introduced DNA was integrated into the chromosome in a multiple tandem array. The mitotic stability of the introduced DNA was increased by a repeated sporulation process. The expression of the Escherichia coli beta-glucuronidase gene in R. delemar was successfully obtained under the control of the pgk2 gene promoter of R. niveus by co-transformation with the pyr4 gene.
