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

Temperature-sensitive (TS), internally deleted and truncated alleles are important tools to facilitate the characterization of essential genes. We have developed a straightforward method to replace a wild-type gene with a mutant allele at the endogenous locus. This method is an efficient alternative to the two-step method for integration of alleles that are compromised in function or contain multiple mutations. A strain is constructed that has the essential gene of interest disrupted by a selectable marker. Strain viability is maintained by a plasmid carrying a copy of the essential wild-type gene and the ADE3 gene. The mutant allele is cloned into an integratable vector carrying a selectable/counter-selectable marker, such as URA3. The plasmid is linearized and transformed, directing integration to the 5' or 3' region flanking the essential open reading frame (ORF). Transformants that have integrated the mutant gene at the endogenous locus can lose the autonomous plasmid carrying the wild-type copy of the essential gene and the ADE3 gene. These transformants are identifiable as white sectoring colonies, display the mutant phenotype and may be characterized. An optional second selection step on 5-fluoroorotic acid (5-FOA) selects for popouts of the integrating vector sequences, leaves the mutant allele at the endogenous locus, and recycles selectable markers. We have used this method to integrate a TS allele of SPC110 that could not be integrated by standard methods.
