Interpret the association of the WMSI and mortality. Use your final model to calculate the hazard ratio(s) for WMSI. If your final model contains a time interaction, use the following ln(time) values; -1.04, 0.104 and 0.443. (These values were calculated by subtracting the ln of the mean time from the ln of 7.5, 23.5 and 33.0. These are the 25th, 50th and 75th percentiles of time.)
