Correlation coefficients between clinical and laboratory variables of patients with juvenile rheumatoid arthritis in relation to their ultrasonographic findings.

	USG knee synovial thickness	USG knee effusion volume
Disease duration (month)	0.18	0.23
AI score	0.74*	0.64*
VAS (cm)	0.21	0.41*
DAS score	0.73*	0.83*
JAFAR score	0.13	0.37
Clinical knee score	0.71*	0.85*
Clinical hip score	0.23	0.15
Hb level (gm/dL)	−0.31	−0.81*
ESR level (mm first hour)	0.61*	0.44*
CRP level (mg/L)	0.51*	0.45*

Notes: Critical value(r) = 0.9; P > 0.05 insignificant; P < 0.05* = significant.

Abbreviations: AI, articular index; DAS, disease activity score; VAS, visual analog scale; JAFAR, juvenile arthritis functional assessment record; Hb, hemoglobin level; ESR, erythrocyte sedimentation rate; CRP, C-reactive protein; USG, ultrasonography.
