Intra- and inter-assay reproducibility of the GPL fatty acid analysis.

<p>Mean and SD are expressed as %wt/wt.</p

Correlation of RBC total PL and RBC GPL omega-3 index (n = 13).

Correlations between RBC GPL fatty acids and other RBC PL fractions before and after n-3 supplementation.

<p>n.s. not significant.</p

Effects of DHA supplementation on fatty acid composition (%wt/wt) of individual RBC PL fractions.

<p>Differences between study start and end were based on baseline values. Paired t-test: *p<0.05, **p<0.01, *p<0.001.</p

Recovery of total RBC fatty acids using different extraction procedures (<i>P</i><0.05).

<p>Recovery of total RBC fatty acids using different extraction procedures (<i>P</i><0.05).</p

Changes in fatty acids (%wt/wt) during storage of RBC samples (n = 13) in methanol over a period of 8 months at −80°C.

*<p>Differences in fatty acid contents caused through sample storage were related to fatty acid contents of samples without storage. Mean and SD are expressed as %wt/wt. n.s.: not significant.</p
