Manova not significant, some Anova tests are. Are they valid?

#1
I"m doing my dissertation on recommendations made during a diagnostic procedure, so I have 19 dependent variables based on 8 diagnosis levels. When I ran SPSS it was not significant, does that mean that none of the relationships are significant? or could some of the individual Anova tests that meet significance levels be valid? (I have 4 Anova's that are less than 0.05. Also are there any additional tests I should look at. I ran Tukey's and LSD but I don't think that they would apply without the significance right? What about Chi square? I'm not sure how that would fit in.


Thanks for any help you might give. David
