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

Meiotic homologous recombination (HR) is important for proper chromosomal segregation during gametogenesis and facilitates evolutionary adaptation via genomic reshuffling. In most eukaryotes, HR is mediated by two recombinases, the ubiquitous RAD51 and the meiosis-specific DMC1. The role of RAD51 in mammalian meiosis is unclear and study of its function is limited due to embryonic lethality of RAD51 knockouts. Here, we developed an in vivo meiotic knockdown and protein complementation system to study RAD51 during mouse spermatogenesis. We show that RAD51 is crucial during meiotic prophase and its loss leads to depletion of late prophase I spermatocytes through a p53-dependent apoptotic pathway. This phenotype is distinct from that observed in the DMC1 knockdown. Our meiotic knockdown and complementation system establishes an experimental platform for mechanistic studies of meiotic proteins with unknown functions or essential genes for which a testis-specific knockout is not possible.
