The growth and reproduction performance of TALEN-mediated β-lactoglobulin-knockout bucks.
Article in Transgenic research, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
With the technological development of several engineered endonucleases (EENs), such as zinc-finger nucleases, transcription activator-like effector nucleases (TALENs) and CRISPR/Cas9, gene targeting by homologous recombination has been efficiently improved to generate site-specifically genetically modified livestock. However, few studies have been done to investigate the health and fertility of these animals. The purpose of the present study is to investigate if gene targeting events and a recloning procedure would affect the production traits of EEN-mediated gene targeted bucks. TALEN-mediated β-lactoglobulin (BLG) gene mono-allelic knockout (BLG (+/-)) goats and bi-allelic knockout (BLG (-/-)) buck produced by using sequential gene targeting combined with recloning in fibroblasts from BLG (+/-) buck were used to evaluate their health and fertility. Birth weight and postnatal growth of BLG (+/-) bucks were similar to the wild-type goats. None of the parameters for both fresh and frozen-thawed semen quality were significantly different in BLG (+/-) or BLG (-/-) bucks compared to their corresponding comparators. In vitro fertilization (IVF) test revealed that the proportion of IVF oocytes developing to the blastocyst stage was identical among BLG (+/-), BLG (-/-) and wild-type bucks. Conception rates of artificial insemination were respectively 42.3, 38.0 and 42.6 % for frozen-thawed semen from the BLG (+/-), BLG (-/-) and wild-type bucks. In addition, germline transmission of the targeted BLG modification was in accordance with Mendelian rules. These results demonstrated that the analyzed growth and reproductive traits were not impacted by targeting BLG gene and recloning, implicating the potential for dairy goat breeding of BLG (+/-) and BLG (-/-) bucks.
