Odds ratios (95% confidence intervals) of 1-year MetS incidence and reversion, and MetS prevalence.

<p>Odds ratios at baseline and 1 year by quartiles of 1-year changes in plasma levels of oleic and α-linolenic acids are shown in the left and right panels, respectively. The lowest quartile was chosen as the reference for the odds ratio calculations. Different superscript letters indicate significantly different 1-year prevalence changes between quartiles (<i>p</i><0.05 by logistic regression model), while an * indicates a significant 1-year prevalence change within each quartile (<i>p</i><0.05 by McNemar's test).
