We have 46-day follow-up data on 345 stroke patients and want to investigate whether the risk of recurrent stroke and/or death depends on the type of stroke (cerebral embolism or not). The results of the multiple logistic regression of the dummy variable for cerebral embolism (1 = yes, 0 = no) and age are shown below.

Calculate the odds ratio comparing the odds of recurrent stroke/death for a patient who is 53 versus 52, controlling for cerebral embolism.
