Parallel Tukey boxplots of the clinical score in pigs. The boxplot is over the first 5 days after inoculation (Day 0) with Actinobacillus pleuropneumonia serotype 2. Benzylpenicillin treatment was initiated at the onset of clinical signs which occurred within 24 h after inoculation. The treatment group nomenclature is: the medicinal product, either procaine benzylpenicillin in a water suspension (ETH) or procaine benzylpenicillin in an oil suspension (UPA); dose in mg/kg; dose frequency (once or twice daily) and treatment duration in days. For example, ETH20-2 × 3 should read as: procaine benzylpenicillin in a water suspension 20 mg/kg bodyweight twice daily for three days
