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

objectiveTo compare the expression of DKKL1 in ejaculated spermatozoa of normal fertile men and men with asthenospermia and investigate the role of DKKL1 in the pathogenesis of asthenospermia.

methodsThe characteristics of semen samples collected from normal fertile men and men with asthenospermia were analyzed using computer-assisted sperm analysis according to WHO criteria. The ejaculated sperms were isolated by Percoll discontinuous density gradients to detect the expression of DKKL1 mRNA and protein using real-time PCR and Western blotting.

resultsThe expression of DKKL1 mRNA was significantly down-regulated by 11.1 times in asthenospermic men as compared with that in normal fertile men (P<0.01). Western blotting showed that the expression of DKKL1 protein was down-regulated by 2.4 times in asthenospermic men compared to normal fertile men.

conclusionThe expression of DKKL1, which may play an important role in sperm motility,is significantly decreased in ejaculated spermatozoa of men with asthenospermia.
