Predicative probability of neurotoxicity in the two groups^a

Groups		Grade of neurotoxicity
		0	1	2	3
	Observed value	19	20	16	5
Experimental group	Predicative value	20.26	18.98	12.98	7.77
	Predicative probability	33.77	31.64	21.64	12.95
	Observed value	13	16	14	17
Control group	Predicative value	11.46	16.55	17.40	14.59
	Predicative probability	19.09	27.58	29.00	24.32

^aThe probability of low-grade (grade 0 and 1) neurotoxicity occurring in the experimental group was higher than in the control group, while the probability of high-grade (grade 2 and 3) neurotoxicity occurring in the experimental group was lower than in the control group.
