Independent variable		# value <cutoff^*	# value >cutoff^*	Misclassification Rate^***	p-value^**
Total Bilirubin (cutoff=6.6)	Mild	20	2	5/33	0.00043
Total Bilirubin (cutoff=6.6)	Severe	3	8	5/33	0.00043
Conjugated Bilirubin (cutoff=4.5)	Mild	6	1	1/13	0.0047
Conjugated Bilirubin (cutoff=4.5)	Severe	0	6	1/13	0.0047

These columns represent the numbers of patients in each classification group with a mean value of the variable above and below the cut-off thresholds.

^**

p-value is two-sided and obtained from Fisher's Exact Test

^***

The misclassification rate is a measure of how often a patient would be classified into the wrong outcome group based on the suggested threshold.
