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

The male alpaca plays an important role in the reproductive process and, consequently, in genetic improvement. South American camelids (SACs) have a well-defined reproductive season, particularly in the Andean region. The objective was to evaluate the influence of reproductive and non-reproductive seasons, as well as testicular volume, on seminal parameters in alpacas. Nine healthy male alpacas, over 4 years old, were selected for this experiment. Semen samples were taken every two days using an artificial vagina incorporated into a dummy. The collected were in the reproductive (November to April) and non-reproductive (May to October) seasons, from breeders with testicular volumes that range between 63-70 cm
