Table 4.

Predictors at first 5 years and 5-year followup associated with outcome at 17-year followup for 86 incidence cases of juvenile chronic arthritis. Univariate correlations with Spearman correlation coefficient are used for comparison between continuous and ordinal variables and chi-square test/Fisher exact test (FET) are used for comparison between categorical variables.
