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

Purpose: Since the developmental competence of oocytes cultured after in vitro maturation (IVM) is low, it is necessary to improve the IVM method for efficient offspring production. In this study, we revealed that transferrin (TF)-Fe Methods: To mimic the follicular development environment, cumulus-oocyte complexes (COCs) were cultured in pre-IVM medium (low dose of FSH) without or with Holo-TF (monoferric or diferric TF) or Apo-TF (non-iron bond TF). After pre-IVM without or with Holo-TF, COCs were cultured in IVM medium (high dose of FSH and EGF) without or with Holo-TF. Results: Cultivation with Holo-TF increased the expression of follicular development maker ( Conclusion: We succeeded in showing for the first time that the cultivation with Holo-TF in pre-IVM can produce embryos in pig with high efficiency.
