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

Events occurring during meiotic prophase I are critical for the successful production of haploid gametes. Many prophase I events are mediated by a meiosis-specific structure called the synaptonemal complex. To date, the limited knowledge we have about the dynamics of these prophase I events in mice comes from fixed, two-dimensional preparations of meiotic cells making it impossible to study the three-dimensional (3D) arrangement of meiotic chromosomes. The current study involves the development of an imaging system to view prophase I events in live mammalian spermatocytes by generating a transgenic mouse, Sycp3-Eyfp ( 21HC ), expressing a fluorescently tagged synaptonemal complex protein, SYCP3. Using this live imaging system, the 3D structural arrangement of chromosomes in the different prophase I substages has been characterized in live spermatocytes, and aspects of the 3D architecture of spermatocytes have been observed that would not be possible with existing techniques. Additionally, chromosome movement in prophase I spermatocytes and meiotic progression from pachynema to diplonema were observed following treatment with the phosphatase inhibitor, okadaic acid (OA), which accelerates the progression of cells through late prophase I. These studies demonstrate that the Sycp3-Eyfp ( 21HC ) live imaging system is a useful tool for the study of mammalian prophase I dynamics.
