Circulating Prokineticin 2 Levels Are Increased in Children with Obesity and Correlated with Insulin Resistance

Table 4

Distribution of patients according to PK2 quartile.

PK2 quartile	Control group	Obese group	OR (95% CI)	P value
Q1	57.2%	16.5%	1	—
Q2	15.7%	16.5%	3.64 (1.37–9.67)	0.01
Q3	21.4%	27.5%	4.44 (1.86–10.64)	0.001
Q4	5.7%	39.5%	24.00 (7.29–78.99)	<0.001

Data are shown as percentages of the total number in each group according to PK2 quartile. OR denotes odds ratio of obese children compared with the group of children with the lowest ranges of concentration of PK2; the likelihood of obesity increases as the level of serum concentration of PK2 increases. PK2, prokineticin 2; Q, quartile; OR, odds ratio; CI, confidence ratio.
