Table 3 Overview of pleurisy scoring systems in slaughter pigs^a

Score	Scoring system
Score	Madec and Kobisch [57]	CTPA ^b	Pointon et al. [66]		SPES ^c
0	No pleurisy
1	Interlobular pleurisy (visceral pleurisy)	Fibrinous pleurisy	Interlobular pleurisy (adhesions between lung lobes)	1 N: pleurisy with normal lungs	Cranioventral lesion: interlobar pleurisy or at ventral border of caudal lobes
1	Interlobular pleurisy (visceral pleurisy)	Fibrinous pleurisy	Interlobular pleurisy (adhesions between lung lobes)	1P: pleurisy with pneumonic lungs
2	Localized pleurisy < 2 cm diameter	Extended pleurisy: lungs cannot be removed from the carcass	Pleurisy (adhesions of lungs to chest wall)	2 N: pleurisy with normal lungs	Dorsocaudal monolateral focal lesion
2	Localized pleurisy < 2 cm diameter	Extended pleurisy: lungs cannot be removed from the carcass	Pleurisy (adhesions of lungs to chest wall)	2P: pleurisy with pneumonic lungs	Dorsocaudal monolateral focal lesion
3	Extensive pleurisy > 2 cm diameter with adhesions to ribcage	–	–		Bilateral lesion of type 2 or extended monolateral lesion (at least one third of one diaphragmatic lobe)
4	Partial or total ribcage condemnation	–	–		Severely extended bilateral lesion (at least one third of both diaphragmatic lobes)

^aThe Danish system [41] is explained in the text but not listed in the table, as it differs significantly from the other systems
