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

From a review of some aspects of epididymal structure, function and research done largely in my research area over the last 50 years, I conclude that more is known than is understood of sperm maturation and storage in the epididymis. Highly qualified technicians have not always applied sophisticated modern techniques in well-considered experiments to physiologically relevant and properly-prepared samples, so that our understanding of the biological problem of the nature of the epididymal epithelial influence on maturing epididymal spermatozoa has not kept pace with the outpouring of data generated, much of which is difficult to interpret. We stand at a crossroads of where to aim our limited resources and personnel: should we continue new technology-led studies in many directions, backtrack to test hypotheses and fill in gaps in our knowledge, or consider more biological directions to our research?
