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

Targeted disruption of the mouse TOP3alpha gene encoding DNA topoisomerase IIIalpha was carried out to study the physiological functions of the mammalian type IA DNA topoisomerase. Whereas heterozygous top3alpha+/- mutant mice were found to resemble phenotypically their TOP3alpha+/+ litermates, no viable top3alpha-/- homozygotes were found among over 100 progeny of top3alpha+/- intercrosses. Examination of embryos dissected from decidual swellings and in vitro culturing of blastocysts from top3alpha+/- intercrosses showed that implantation of top3alpha-/- embryos and the induction of decidualization could occur, but viability of these embryos was severely compromised at an early stage of development. The requirement of mouse DNA topoisomerase IIIalpha during early embryogenesis is discussed in terms of its plausible role in chromosome replication and its interaction with the RecQ/SGS1 family of DNA helicases, whose members include the Bloom's syndrome and the Werner's syndrome gene products.
