Hi all:

I got a Statistics question of Homogeneity of Odds Ratios P-Value

If Cardiac SSRI Therapy has 5 subgroups, is it true that Homogeneity
odds Ratios of P-Value is Blank ? In other words, the test is
meaningful ONLY when all trts has >=1 AE count?

Using SAS I got 0.258 for odds ratio for Cardiac ,but the
statistician said that we need to reset it to blank since every row
should has >=1 counts (see Total column) to get meaningful p-value. I
am not convinced

Please advise.
Thanks lot .
