1. Comparison of mean Schirmer tear test (STT)-1 results (mm/min) in 30 dogs before (STT-1a) and after (STT-1b) administration of acepromazine (0.02 mg/kg) and methadone (0.3 mg/kg).
Comparison of mean Schirmer tear test (STT)-1 results (mm/min) in 30 dogs before (STT-1a) and after (STT-1b) administration of acepromazine (0.02 mg/kg) and methadone (0.3 mg/kg). There was a significant decrease in STT-1 results after acepromazine/methadone administration. Box represents the IQR with median value and whiskers at the 10th and 90th percentiles (significance set at P<0.05).
