Analysis of the expression levels and daily rhythmicity of lipid metabolism related-genes by COSOPT or R analysis in rat retina and liver.

<p>Amplitude, mean amplitude of the identified time series (theoretically zero); Period, mean period of the identified time series (theoretically 24); Phase, mean time of acrophase of the identified time series (theoretically zero); pMMC-Beta, mean multiple measures corrected significance probability β value. Genes with a period of between 20 and 28 hr with pMMC-β value of <0.05 were considered circadianly regulated. <i>Pr</i> values have been calculated by the single cosine R analysis. Genes with <i>Pr</i> value of <0.05 were considered circadianly regulated. *p<0.05, **p<0.01, ***p<0.0001.
