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

backgroundThe aim was to determine seminal osmolarity in S. collinsi and evaluate whether it, along with seminal parameters, varies between fattening and non-fattening conditions and across age groups.

methodsBiometric and seminal parameters were evaluated in nine S. collinsi males across conditions. Mixed-effects models assessed reproductive parameters and seminal quality.

resultsSeminal osmolarity ranged from 300 to 500 mOsm/L and varied with age and fattening condition. Testicular volume was lower during non-fattening. Seminal osmolarity showed linear and quadratic associations with reproductive biometry and sperm quality. Seminal volume decreased with increasing osmolarity, whereas sperm morphology and vigor showed non-linear associations. Age was negatively associated with plasma membrane integrity and sperm morphology, while sperm concentration and motility were not significantly affected.

conclusionSeminal osmolarity and age are associated with reproductive and sperm functional parameters, establishing the first baseline for seminal osmolarity in this species and supporting reproductive biotechnology and conservation strategies.
