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

Research on genetically engineered mice provides insights into the etiology, therapy, and genetic basis of human diseases. An important variable that affects the results of mouse studies is the health status of the animals. Pathogen burdens may confound observations and obscure underlying mechanisms. Mouse resource centers frequently rederive infected mouse strains. We review our experience on the use of a well-established technique, embryo transfer to rederive infected mouse strains. The following mouse pathogens were eliminated by embryo transfer: Mouse Parvovirus, Mouse Hepatitis Virus, Mouse Rotavirus, Mouse Encephalomyelitis Virus, Mouse Adenovirus, Helicobacter species, endoparasites, and ectoparasites. We rederived transgenic mouse lines, gene-targeted mouse lines, and lines with spontaneous mutations. In the majority of strains, fertilized eggs for embryo transfer were obtained by mating superovulated egg donors with males of the desired genotype. A total of 309 embryo transfers were performed to rederive 96 mouse strains. The pregnancy rate was 76%; 1996 pups were born, of which 43% carried the desired genotype. We performed 44 additional embryo transfers to rederive 15 other strains. The pregnancy rate was lower (45%) and none of the 135 pups carried the desired genotype. Although we successfully eliminated the pathogens in all transfers, we were unable to obtain pups with the desired genotype in 15 of 111 mouse lines. Multiple factors affect the efficiency of rederivation by embryo transfer. They include the response to superovulation by embryo donors, the number and age of stud males, the yield of fertilized eggs, the number of embryo transfers, and genotyping.
