Value of simplified lung lesions scoring systems to inform future codes for routine meat inspection in pigs

Table 1 Summary of the lung scoring systems for the evaluation of cranioventral pulmonary consolidation (CVPC) at batch level

Scenario ID	Description of the scoring system	Measurable outcome at batch level
Scenario ID	Description of the scoring system	Prevalence	% of affected lung surface	N lobes affected
Gold standard	Detailed description in section”Lung lesion scoring at slaughter”	Yes	Yes	Yes
Scenario 1 Presence or absence of CVPC	CVPC was scored as present [1] or absent (0) for each pair of lungs	Yes	No	No
Scenario 2 German scoring system	CVPC was scored as mild (lesions affecting < 10% of the lungs surface), moderate (10–30%), and severe (> 30%)	Yes	Yes	No
Scenario 3 Number of lung lobes affected	CVPC was assessed in each lung lobe. The number of lung lobes affected was recorded (0–7)	Yes	Yes^a	Yes
Scenario 4 Number of lung lobes affected excluding the intermediate lobe	Pneumonia lesions were assessed in both apical, cardiac and diaphragmatic lobes. The number of lung lobes affected was recorded (0–6)	Yes	Yes^b	Yes

^a% of lung surface affected was calculated attributing the same lobe weight to all lobes (n = 7)
^b% of lung surface affected was calculated attributing the same lobe weight to all lobes (n = 6)
