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

In this study, we aimed to determine whether the main mitochondrial DNA (mtDNA) haplogroups of the Han people have an impact on spermatozoa motility. We recruited 312 men who were consecutively admitted to two affiliated hospitals of College of Medicine, Zhejiang University from May 2011 to April 2012 as part of fertility investigations. Semen and whole blood samples were collected from the men. We determined the mtDNA haplogroups by analysing the sequences of mtDNA hypervariable segment I and testing diagnostic polymorphisms in the mtDNA coding region with DNA probes. No significant differences were found in the clinical characteristics of the mtDNA haplogroup R and non-R (P>0.05). Our results suggest that mtDNA haplogroup R is a strong independent predictor of sperm motility in the Han population, conferring a 2.97-fold (95% confidence interval: 1.74-4.48, P<0.001) decreased chance of asthenozoospermia compared with those without haplogroup R.
