Fig. 14From: Tests of trend between disease outcomes and ordinal covariates discretized from underlying continuous variables: simulation studies and applications to NHANES 2007–2008Power for time-to event outcomes generated by Eq. (6) with a hazard ratio of 1.05 for a unit increase in BMI. The setup denotes a weak linear alternative in which the logarithm of the hazard ratio increases linearly at a moderate rate with increasing BMIBack to article page
