|Variable||OR (95% CI)|
|APCR||1.51 (0.73 to 3.13)|
|aPL-positive at baseline||2.19 (1.04 to 4.61)|
|APCR AND aPL-positive at baseline†||3.31 (1.30 to 8.41)|
|Study recruitment group||12.02 (3.59 to 40.31)|
*Thirty-nine events were observed in 404 persons. Eleven individuals were not included in the regression model because of missing APCR status. Of these, 2 had a venous thrombosis.
†OR for APCR with aPL = product of ORs for each. The corresponding 95% CI was calculated using a covariance matrix.
