  • *The constant shows the utility at randomisation for a patient without any of the risk factors included in the analyses. A negative (positive) sign indicates that the risk factor is associated with a lower (higher) utility at randomisation.

  • †Note that coefficients represent the gain in utility in the early interventional strategy over and above that of the conservative strategy.

  • SE, standard error.
