A sub-set of the Framingham study data set was analysed using Kaplan-Meier survival methods to determine survival without developing coronary artery disease. Subjects were followed for up to 24 years. The attached figure shows the Kaplan-Meire survival curves comparing male and female subjects. Survival Probability 1.0 0.8- 06- 04- 02- 0.0- Female Male 0 Product-Limit Survival Estimates With Number of subjects at Risk and 95% Confidence Limits 3279 1005 1434 2000 4000 6000 Time (days) to outcome event or censoring Sex of subject Female Male 8000 Which is the following statements is true? a) Males are statistically less likely to get CHD than females during follow-up. b) Females are statistically less likely to get CHD than males during follow-up. c) Males are less likely to get CHD than females during follow-up but we can say nothing about the statistical significance of the lower survival d) Females are less likely to get CHD than males during follow-up but we can say nothing about the statistical significance of the lower survival e) Nothing can be said about the difference in survival between males and females without numerical estimates of the survival probability for the two groups.
