Figure G5 is a forest plot of the sensitivity and specificity of IgM-rheumatoid factor test for polyarticular juvenile idiopathic arthritis. It includes 8 studies: Andersson-Gage 1994, Ferreira 2007, Haynes 1986, Lipinska 2008, Roizenblatt 1983, Saulsbury 1990, Varbanova 1999, and Wernick 1981. Senisitivity ranged from 0.00 (95% CI: 0.00, 0.34) in Roizenblatt to 0.55 (95% CI: 0.32, 0.77) in Varbanova. Specificity ranged from 0.93 (95% CI: 0.82, 0.99) in Ferreira to 1.00 (95% CI: 0.94, 1.00) in Varbanova.
