Lymphocyte counts (A) and blood glucose levels (B) of cats in groups 1 and 2. Values are depicted as mean +/- standard deviation. Black arrows = methylprednisolone administration. Cats in group 1 received the methylprednisolone administrations; cats in group 2 served as untreated control animals. A) Cats in group 1 had significantly lower lymphocyte counts than cats in group 2 (pMWU < 0.05) starting after the first methylprednisolone administration until day 70. B) Cats in group 1 had significantly higher blood glucose levels than cats in group 2 (pMWU < 0.05) starting after the first methylprednisolone administration at all collection time points with the exceptions of days 2, 11, and 36.
