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

Bovine embryo transfer (ET) has been a consistently growing market worldwide with in vitro produced (IVP) embryos now far outnumbering those produced by traditional superovulation. Because transfer of a viable blastocyst-stage embryo to the uterus bypasses many of the potential biological causes of early pregnancy failure associated with artificial insemination (AI; anovulation, sperm transport, fertilization failure, early embryonic death), pregnancy success should logically be higher following ET than following AI. However, this is not always the case. One of the main factors contributing to this paradox is pregnancy loss following ET, particularly with IVP embryos. This greater embryo mortality presents a significant obstacle to more widespread use of IVP embryos. Improvements in embryo culture media as well as in our understanding of the underlying physiological and molecular regulation of early embryo development and embryo-maternal communication leading to a successful pregnancy will significantly contribute to improved reproductive efficiency and sustainability in agri-food production.
