Table 1.

Potential risk factors for dyslipidemia in 202 private care and 424 public care patients with rheumatoid arthritis. Data were compared between private and public care patients by the chi-square test (dichotomous variables) and Student t test (continuous variables). Characteristics that differed (p < 0.05) between the 2 groups are shown in bold type.
