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

Accurate determinations of acrosome reaction (AR) are fundamental to obtain physiologically relevant information of this essential event for sperm fertilization. For decades, the AR was exclusively studied in fixed preparation; more recently, new methods were developed to evaluate the AR in live sperm and in real time. These new technologies involved the use of genetically modified mice models, dyes with ion affinity, and fluorescent microscopy. In addition, these techniques allowed the reproduction field the possibility to follow the AR directly in the female tract under physiological conditions. Despite these advances, maintaining transgenic colonies is expensive for most research laboratories. Here, we present a methodology which can be mounted in a simple epifluorescence microscopy set in combination with appropriate filters enabling to follow the AR in real time. The implemented technique allows also to follow the AR in combination with [Ca
