  1. aCI, Confidence interval; RNAP+, positivity for anti-RNA polymerase III antibodies; RNAP-, anticentromere antibodies, anti-Scl-70, antinuclear antibody-negative and other antibodies. These analyses include all events (row 2A) with total frequency N = 2,177, 437 cases dropped, 128 events, 1,612 censored; events post-systemic sclerosis onset (row 2B) with total frequency N = 2,177, 483 cases dropped, 83 events, 1,611 censored; and for events within 36 months of systemic sclerosis onset (row 2C) with total frequency N = 1,623, 6 missing cases, 42 events.
