Models 3a and 3b are reparameterizations of one another with an identical model fit and explanatory power. Model 3a demonstrates the impact of marriage to a spouse with no history of registration for alcohol use disorder and then shows the additional risk involved if that spouse has a history of alcohol use disorder (increasing risk ~3.4-fold). Model 3b reparameterizes this to allow us to compare directly the risk association with marriage to aspouse without versus aspouse with a history of registration for alcohol use disorder (hazard ratios of 0.38 versus 1.29).
