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.
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
During spermatogenesis, mammalian male germ cells undergo multiple developmental processes, including meiosis and post-meiotic differentiation (spermiogenesis). To understand the transitions between different cellular states it is essential to isolate pure populations of cells at different stages of development. Previous approaches enabled the isolation of cells from different stages of meiotic prophase I, but techniques to sub-fractionate unfixed, post-meiotic spermatids have been lacking. Here we report the development of a protocol enabling simultaneous isolation of cells at different stages of meiotic prophase and post-meiotic differentiation from testes of adult mice. This approach builds on existing fluorescence activated cell sorting protocols designed to purify cells in different stages of meiotic prophase I. By utilizing the specific spectral properties that two different DNA dyes (Hoechst 33342 and SYTO 16) exhibit when bound to chromatin of different stage male germ cells, we obtain highly pure populations of cells in relatively large numbers. This FACS protocol will enable immunocytological and molecular characterization studies of fractionated meiotic and haploid germ cells from both wild type and genetically mutant animals.
