Autoantibodies detected in the sera of systemic sclerosis (SSc) patients by radioimmunoprecipitation assays, and their clinical associations

Figures in parentheses are percentages.*¹P < 0.05; *²P < 0.01; *³P < 0.005; *⁴P < 0.001 when compared with the respective remaining group; *⁵P < 0.05 when compared with each other; *⁶P < 0.025 when compared with each other; *⁷P < 0.025 when compared with each other; *⁸P < 0.025 when compared with each other; *⁹P < 0.005 when compared with each other; *¹⁰P < 0.005 when compared with each other; *¹¹P < 0.001 when compared with each other (all comparisons by χ² test with Yates' correction where appropriate).
