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

Transgenic B6C3F1 mice carrying a lacI target gene were exposed to acute and multiple doses of ethylnitrosourea (ENU), and germ cells from the seminiferous tubules were assayed for mutation 3 and 90 days after treatment. Relative to untreated controls, the mutation frequency increased 3.2- and 19.9-fold at 3 and 90 days after treatment, respectively. Mutant lacI genes recovered from untreated and treated groups were sequenced, and the spectra of mutations were determined. Eighty-five percent (11/13) of the spontaneous mutations resulted in G.C-->A.T transitions, all of which occurred at CpG dinucleotides. Fifteen of 22 sites (68%) found mutated 3 days after ENU treatment occurred at G.C base pairs, although some of these are expected to be spontaneous mutations. Ninety days after treatment, 13 of 19 sites (68%) found mutated occurred at A.T base pairs. The mutation spectra seen are consistent with proposed mechanisms of ENU mutagenesis and correlate with the in vivo spectra seen in ENU studies by using transmissibility assays and the hprt gene. These findings represent significant progress toward defining the in vivo spectra of ENU mutagenesis in mammalian germ cells.
