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

Ligase chain reaction (LCR) was evaluated as a tool for the detection of point mutations. For the mutation studied, the specificity of the method is sufficient to detect the mutant allele in the presence of a 200-fold molar excess of the wild-type sequence. LCR was therefore employed in a genetic recombination experiment as a probe for a recessive lethal point mutation. LCR greatly facilitated the isolation of a rare recombinant originating from a crossover event in the 40 kb interval separating the lethal mutation and an enhancer trap insertion in the optomotor-blind locus. The recombinant will allow the study of gene control in situ, in a largely unperturbed regulatory environment.
