Or may I calculate the difference in length of stay between the case
and controls within each matched strata and analyse this outcome?
Dear Roland,
as far as length of hospital stay is concerned, you may use ANOVA.
Should your data depart that much from normality, I would suggest you to
perform a bootstrap-ANOVA, in order to test for the robustness of the ANOVA
F test and related significance.
HTH and Kind Regards,
Carlo
