ACE and sarcoidosis: The estimated marginal mean values of serum ACE level for the patients with AS, BD, presumed latent TB and presumed latent syphilis were 29.360, 31.392, 32.500 and 30.452 U/L respectively which were lower than the estimated marginal mean value of ACE for presumed sarcoidosis, but higher than the estimated marginal mean value of ACE for control group (Fig. 1).
