Thanks for quick and informative responses!
And thanks Andy for pointing out the similarity to separation as in logistic regression, though I'm thinking that this is a case of quasi-complete separation rather than complete separation since there are non-treated patients with and without recurrence, but no treated cases with recurrence. So the only cell with zero-frequency would be the "treated-with-recurrence" - am I right?

I'll try and email the corresponding author of the paper and see if I can get the functions.. Wish me luck :)
