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

The molecular defect in an opaque-2 (o2) mutant, previously characterized as a null allele, has been identified as containing an insertion of the transposable element of the Bergamo (Bg) family. Restriction mapping and partial sequence analysis of the Bg in the o2 null allele indicates that this element is distinct from the previously described Bg as well as the defective Bg (rbg) of the o2m(r) allele. It is, however, inserted at the same site in O2 as the rbg of o2m(r) and can transpose when Bg is present. This study shows that, depending on genetic background, this allele may not behave as a stable null which could dramatically influence the conclusions drawn from experiments based on this particular mutant.
