No, you did not read the full study but instead you arrogantly draw hasty
conclusions. The full study states:

Your referred Table 1 as evidence for "harmfullness" of eggs, I used
the same evidence for the "harmfullness" of monounsaturated fat. In
reality neither eggs nor monounsaturated fat are harmful, you just
presented a very crude study.

"After adjusting for saturated fat and cholesterol, as we have done our
analyses, there was a significant negative association of monounsaturated
fat with CHD mortality."

: As for cheese, its correlation with CHD mortality rates is about the
: same as magnesium's, which is not exactly regarded as health hazard.
: Both correlations are, however, nonsignificant and therefore just
: random noise.

If the correlation almost significant you can hardly call it random noise.

Correlation of .27 is very low and if it's also nonsignificant, it is
very likely random noise. If you think it is not, what is your take on
magnesium then, which had almost exactly the same (nonsignificant)
correlation?

Cheka out also the following citation about countries with
cholesterol-Saturated Fat Index (CSI) of 20 or more per 1000 kcal from
the page 7:

"In addition, cheese was inversely related (r= -.69, P=.002)."
