The value of the @R05280@, expressed in @P04483@. It can be calculated from the relative @S05911@ by multiplying by 100. Comment: It is recommended that the 'relative @S05911@' be reported, rather than the 'percentage @S05911@', in order to avoid confusion where results themselves are expressed as percentages. The term '@C01124@ of variation' in place of 'relative @S05911@' is not recommended.
