Variable	Logistic Regression		Likelihood Function Analysis
	OR (95% CI)	P Value	LR
Abnormal RUS findings	4.89 (1.99–12.01)	.001	742.9
DBP z scorea	3.33 (1.49–7.46)	.003	–
Young age (5–11.9 y)	2.22 (1.09–4.53)	.03	22.9

Abbreviations: DBP, diastolic blood pressure; OR, odds ratio (OR >1 and P<.05 statistically significant); LR, likelihood ratio (between 1 and 8 = weak evidence, between 8 and 32 = moderate evidence, and >32 = strong evidence); RUS, renal ultrasound. ^aFor the 12‐ to 19‐year‐old age group.
