Table 3 The weighting of points in each sector used to assess how the positioning of points affects estimates of ln (HR) and var. ln (HR)

From: A non-linear optimisation method to extract summary statistics from Kaplan-Meier survival plots using the published P value

  1. The maximum timeframe was split into three equal sectors as described. A series of weighted sets were created for each study based on distributing 30 points at specific weights across each of the sectors
