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

Research has determined that the percentage morphologically normal sperm in bulls is highly repeatable and strongly correlated with days to conception and calf output in both dairy and beef herds. Currently, however, standardization of the assessment of morphology between laboratories is lacking, leading to inability of the practitioner to gain meaningful evaluations that relate to bull fertility.Here we outline protocols that permit a standardized approach among laboratories that has been successfully used for 20 years. The scheme includes skill updates and training of laboratory personnel along with annual examination of their work. This results in a reliable analysis and report which is easily interpreted by practitioners and used as part of the standard BBSE.This model has enabled increased accuracy of prognosis for practitioners and is well regarded both in Australia and overseas.
