Refinements for embryo implantation surgery in the mouse: comparison of injectable and inhalant anesthesias - tribromoethanol, ketamine and isoflurane - on pregnancy and pup survival.
Article in Laboratory animals, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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.
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
An essential aspect of genetically-engineered mice (GEM) is the ability to produce live animals after the appropriate injection procedure. Animals are produced by implantation of manipulated embryos into pseudopregnant females for gestation, parturition, and growth to the weaning stage. This study was carried out to test whether the anesthesia used during surgery could affect the number of pups produced. Anesthetics commonly used for implant surgery include tribromoethanol (Avertin) delivered by intraperitoneal (IP) injection, IP-injected ketamine:xylazine or ketamine:medetomidine mix, and inhaled isoflurane. To determine if the anesthesia used might affect the number of animals produced, each anesthetic agent was tested in implant surgeries and the numbers of pups produced using both wild-type and GEM embryos were assessed. Parallel studies were conducted in institutions in the EU and in the USA. Based on a direct comparison of pregnancy status, number of pups born, and number of pups weaned for each agent, we found no statistical differences among the three anesthetics. We conclude that all three anesthetic agents tested are equally useful for implantation surgery.
