The heritability values show an increasing trend with age and in the course of the entire ontogenetic development two age periods were remarkable.
As PSLWA is added, the reduction rate of interior humidity in stage II is obviously reduced and the reduction trend with age changes from non-linear pattern to almost linear pattern.
A chronological increasing trend with age of most sperm quantitative and qualitative traits (semen volume, sperm concentration, total sperm number per ejaculate, plasma membrane integrity, viability, acrosomal integrity and semen quality factor) was observed.
GGT did not show a significant trend with age.
Tests for a trend with age were carried out using logistic regression with above or below the median as the response variable and age as the independent variable.
Cluster 1 represents genes that increase in expression with age, while as Cluster 2 represents genes that decrease in expression with age. Figure 1b and 1c shows the medoid (the gene which most epitomizes the behavior of the cluster) for clusters one and two, showing a clear trend with age for genes associated with clusters one and two.
No trend with age was seen.
BMI, WC and HC showed an increasing trend with age.
No clear trend with age at first birth remained in our age-adjusted analyses, however.
Relative expression levels of miR-23a showed an increasing trend with age.
There was a trend of decreasing survival with increasing deprivation, but no trend with age.
