Webdistance scales the distance to the variance in each observation based on the covariance matrix. [(X 1-X2) TC-1(X 1-X2), where C is the covariance matrix of covariates X1 and X 2]. Thus, the metric is weighted by the variance in each direction. Web1. Introduction. In biomedical studies, it is common to observe outcome event times that are subject to right censoring. In the presence of right censoring, the underlying true event time is greater than the censoring time but the exact value is unknown.
WebThe IPTW analysis showed the similar results (Table 2). After matching, the median OS in surgery-alone group was 62 months versus 79 months in postoperative chemotherapy group, showing a better OS outcome in postoperative chemotherapy group (p < 0.01).
