Table 4 Pearson correlation coefficients for the installed seven sensors between laboratory somatic cell score (LSCS) and predicted somatic cell score (PSCS) determined with data from the validation data set, and the differences (∆) between the correlation coefficients as the quality of the calibration approach

From: Calibration of an automated California mastitis test with focus on the device-dependent variation

Sensor	Parameter¹	OSCS	LSCS	∆
1	LSCS	0.57	-	0.10
1	PSCS	-	0.67	0.10
2	LSCS	0.22	-	0.40
2	PSCS	-	0.62	0.40
3	LSCS	0.33	-	0.33
3	PSCS	-	0.66	0.33
4	LSCS	0.20	-	0.37
4	PSCS	-	0.57	0.37
5	LSCS	0.49	-	0.13
5	PSCS	-	0.62	0.13
6	LSCS	0.51	-	0.10
6	PSCS	-	0.61	0.10
7	LSCS	0.26	-	0.34
7	PSCS	-	0.60	0.34

P < 0.0001; ¹OSCS = on-line somatic cell score (log2(OSCC/100) + 3); LSCS = somatic cell score (laboratory determined; log2(LSCC/100) + 3); PSCS = predicted somatic cell score; ∆ = IdifferenceI.
