Intercept of model predicting OV = −4.2, C-index: 0.878, = 0.31, .
Intercept of model predicting LOV = −4.2, C-index: 0.850,  = 0.30, .
Beta: coefficient estimates, OR: odds ratio, SE: standard error, CI: confidence interval.
Platelet count dichotomized by the median value because of large value of coefficient estimates of platelet count (−10-5) when used as continuous variable not corrected by the exact method, Logistic regression analysis was computed on 110 patients due to one missing value in those with no OV.
