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

Precise coordination of meiotic progression is a critical determinant of an egg's capacity to be fertilized successfully, and zinc has emerged as a key regulatory element in this process. An early manifestation of a regulatory role for this transition metal is the significant increase in total intracellular zinc. This accumulation is essential for meiotic progression beyond telophase I and the establishment of meiotic arrest at metaphase II. The subsequent developmental event, fertilization, induces a rapid expulsion of labile zinc that is a hallmark event in meiotic resumption. In the present study, we show that the zinc fluxes work, in part, by altering the activity of the cytostatic factor (CSF), the cellular activity required for the establishment and maintenance of metaphase II arrest in the mature, unfertilized egg. We propose a model in which zinc exerts concentration-dependent regulation of meiosis through the CSF component EMI2, a zinc-binding protein. Together, the data support the conclusion that zinc itself, through its interaction with EMI2, is a central component of the CSF.
