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

Chromatin structure during meiosis is different from somatic cells due to the assembly of the synaptonemal complex between homologous chromosome axes. However, genome-wide organizing principles of this meiosis-specific multiprotein complex remain mysterious despite intensive super-resolution imaging analysis. Here, we profiled chromatin occupancy of SYCP3, the key chromatin organizer of synaptonemal complex, in mouse spermatocytes, and showed its enrichment at open chromatin regions. Moreover, SYCP3 occupancy was largely inherited from the leptotene to pachytene stage, facilitated by transcription and fibrous assembly, and was enriched at specific SINE repeats. We also identified SYCP1-occupied regions mainly as a subpopulation of SYCP3-occupied regions with high cohesin enrichment. Collectively, our results demonstrate genome-wide profiling of SYCP3 in mouse meiosis and reveal that its occupancy is a dynamic process modulated by chromatin-related events.
