Baseline values were carried forward in cases of missing data.Range of standard deviation for all 4 diet groups was from 1.9 to 3.5. Figure Legend:

HDL indicates high-density lipoprotein. The curves inall 3 plots indicate the linear regression functions for each diet group.For difference between diet groups, P =.48 for total/HDLcholesterol ratio; P =.57 for C-reactive protein;and P =.31 for insulin level.
