On the other hand, the literature on inter-individual variation in gene expression in inbred mice is both limited and somewhat inconsistent.

Our results agree quite well with several recent reports in which inter-individual variation in gene expression is explicitly examined.

Each of these factors may vary from patient to patient (inter-individual variation), and indeed in the same patient over time (intra-individual variation).

In clinical trials, inter-individual variation is a critical measurement used to assess the bioavailability differences from patient to patient in order to ensure predictable dosing.

However, due to the large intra- and inter-individual variation of maternal E4 plasma levels during pregnancy this appeared not to be feasible.

Many studies on both human, and non-human, animals suggest that inter-individual variation in adult aggressiveness is largely organised by prenatal exposure to androgens.

Due to inter-individual variation, incubation period is always expressed in a range.

We did not quantify enzyme levels and therefore the inter-individual variations of spontaneous recovery times are difficult to be interpreted.

It should also be noted that for the liver data, inter-individual variation was examined.

Several researchers have reported differences in the relative gland weights attributing them to factors like seasonal changes, habitat, body weight, inter-individual variations, and gender.
